    Strengthening families through biblical principles.

    Focus on the Family addresses the use of biblical principles in parenting and marriage to strengthen the family.

Paul was very clear in his letter to the Galatians 3 onwards that going back to put yourself under the Law is wrong
He says in Gal 5:4 You are severed from Christ, you who would be justified by the law; you have fallen away from grace.

Paul declares that he is not under the law.
T
o the Jews I became as a Jew, in order to win Jews; to those under the law I became as one under the law--though not being myself under the law--that I might win those under the law. To those outside the law [Gentiles] I became as one outside the law--not being without law toward God but under the law of Christ--that I might win those outside the law. (1Cor 9:20-21)

Hebrews says there is a change in the law.
When there is a change of priesthood, there is necessarily a change of law as well. (Heb 7:12)

The Old (Mosaic Covenant has been replaced:

On the one hand, a former commandment is annulled because of its weakness and uselessness, for the law brought nothing to perfection; on the other hand, a better hope is introduced, through which we draw near to God. (Heb 7:18-19)

For if that first covenant had been faultless, no place would have been sought for a second one. But he finds fault with them and says: “Behold, the days are coming, says the Lord, when I will conclude a new covenant with the house of Israel and the house of Judah. (Heb 8:7-8)

When he speaks of a “new” covenant, he declares the first one obsolete. And what has become obsolete and has grown old is close to disappearing (Heb 8:13)

He takes away the first to establish the second (Heb 10:9)

We are now living under the New Law of the New Covenant. This New Law is written on our hearts. Hebrews 8:8-10 quotes Jeremiah 31:31-33:
Behold, the days are coming, says the Lord, when I will conclude a new covenant with the house of Israel and the house of Judah. It will not be like the covenant I made with their fathers the day I took them by the hand to lead them forth from the land of Egypt; for they did not stand by my covenant and I ignored them, says the Lord.

But this is the covenant I will establish with the house of Israel after those days, says the Lord: I will put my laws in their minds and I will write them upon their hearts. I will be their God, and they shall be my people. (Taken from Heb)

So what is this New Law? It is the Commandments of Jesus:
If you love me, you will keep my commandments.
(Jn 14:15)

If you keep my commandments, you will remain in my love, just as I have kept my Father’s commandments and remain in his love. (Jn 15:10)

Jesus never commanded us to keep a 7th day sabbath.
This is where I think I'm getting off topic but my question really comes down to, who or what is the house of Israel? Is it or are they strictly a direct descendent of Abraham or is it something more? John the Baptist spoke of this too in Matthew 3:8-9 when he told the Pharisees and Sadducees:

8 Therefore bear fruits worthy of repentance,
9 and do not think to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones.
NKJV

The way I understand the verses I've been referencing, it is possible that all believers are part of the family of Israel for we have been grafted to be partakers of the root (Jesus) and ergo, joint heirs with Christ.
 
The Ten Commandments were given to the Jews alone as their covenant law. They were not given to gentiles. It was a sign of their covenant.
The sabbath commandment is the longest of the commandments which indicates that God had to really ram it home to them.
Then why does the Catholic Church have the ten commandments hanging on their wall if they are only for the Jews to follow.

Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.

Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

(I do not want to make this about a discussion of the laws so please keep this on topic)

I asked you a question as your reply has nothing to do with what I asked you in post #57, but will not beg you to answer it.
 
So, you have no answer to my points.
I thought that would be the case.
your points need to be made by using supporting scripture like we are doing. Most things outside of scripture is only one's own point of view without any support. We can respect each others points of view, but do not always agree with them.

God rested on that particular 7th day. It doesn't say God rested every 7th day, any more than he created plants every 3rd day or fish and birds every 5th day.
No one is saying God rested every 7th day, but that we are commanded to keep the 7th day Holy unto God in remembrance of His creation as He sanctified it as a Holy day as He is Holy.

Gen 2:3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

Exo 20:8 Remember the sabbath day, to keep it holy.

Argument 7: Early Christian Believers Met on Sunday


Another argument used to affirm the sacredness of Sunday is created from “cherry picking” the writings of early church fathers such as Barnabas, Justin Martyr, Didache, Ignatius, Dionysius, Clement of Alexandria, and Tertullian. This argument maintains these writers affirmed that early Christians met on Sunday for worship. This approach to the problem of Sunday sacredness is a smoke screen to hide the fact that the New Testament says nothing about Sunday becoming a holy day. Everyone knows that if certain historical facts are kept from sight, people can twist them to create a skewed view of history and make it be whatever they want. However, when all of the historical facts are presented, they tell a very different story than what is often represented as history.


During the first century A.D., Christianity spread throughout the Roman Empire because of persecution. Christians were constantly on the move to escape capture, confiscation, punishment, and death. For a while, each Caesar seemed to be more intent on destroying Jews and Christians than his predecessor. Therefore, early Christians made theological compromises to survive. During the second century A.D., Judaism’s influence over Christianity in Italy had faded because three or four generations of Roman-born Christians had come and gone. Jerusalem was a non-important heap of ruins and Christians wanted their own religious identity – an identity that had nothing to do with the Jews.


To make matters worse, many Gentiles had “joined the church” and brought their peculiar religious baggage. Consequently, Christianity in Rome mutated into a Romanesque version, which was unlike Christianity in other parts of the world.


By A.D. 150, 120 years after Jesus ascended, Christians, in Rome, had found areas where compromise was possible with Mithraism. This led to theological ecumenism and apostasy. Many Christian denominations are participating in a similar process today and again, the result will be awful.

When Rome destroyed Jerusalem in A.D. 70, Christianity was deprived of its headquarters and “main office.” Each church quickly found itself alone and became its own authority in matters of faith and doctrine. Early Church history indicates that Christians adjusted beliefs and doctrines as needed, depending on location and leadership. During the last part of the second century A.D., Irenaeus, the Bishop of Lyons, located in what is now called France, became alarmed with
the heresies that had infiltrated the Christian movement. He was aware of how Christians in Rome had begun to meet on Sunday and abandoned the seventh day Sabbath, and he spoke against it. He wrote: “For He [Christ] did not make void, but fulfilled the law [Ten Commandments].” (Irenaeus, Ante-Nicean Christian Library/Against Heresies, Vol 1, (Boston, 1887) p. 471, insertions mine)


Tertullian, another early church father, wrote extensively concerning Christian doctrine. He, like Irenaeus, was alarmed at the practices of certain Christians, especially those in Rome. In regards to the seventh day Sabbath he wrote: “Thus


Christ did not at all rescind the Sabbath. He kept the law [Ten Commandments] thereof . . . He restored to the Sabbath the works for were proper for it.” (Tertullian, Ante-Nicean Christian Library/Book IV, Chap 12, Vol 3, (Boston, 1887)
p. 362, insertion mine)


Debate over Sunday observance grew in those early years because the church in Rome defended the practice. Bishop Archelaus responded to bishop Manes, saying: “Again as to the assertion that the [seventh day] Sabbath has been abolished we deny that He [Christ] has abolished it plainly. For He Himself was also Lord of the Sabbath.” (Archelaus, Ante-Nicean Christian Library/The Disputation with Manes, Vol 4, (Boston, 1887) p. 217, insertions mine)


By A.D. 320, confusion and compromise had devastated many early Christian beliefs. Christians in Alexandria, Egypt were defending views on the deity of Jesus that opposed the church in Rome. The Christian leaders discussed, debated, and argued the need for centralized church authority and leadership. Many agreed that church doctrine needed to be de ned and protected so that heresy would not destroy Christianity, but they could not agree on a process or who would do the job best.


Poor communication, distance, differences in culture, education, language, and social factors began to define Christianity according to geography. It was easy to see the result would be a highly fractured church. Both the world and Christianity needed a strong unifying leader and Constantine concluded he was “the chosen one!” He believed God had divinely appointed him to rescue a crumbling Roman empire and the universal Christian Church. When Constantine ascended to the throne as sole ruler of the empire, about A.D. 312, he had transformed himself into a Christian for political advantage. Constantine was clever and saw Christianity as
a means of unifying an ethnically and religiously diverse empire. When he endorsed the version of Christianity that was centered in Rome, he set a sequence of events in motion that could not have been imagined.


To put the empire on notice that Constantine had established a new world order, he had his army baptized into Christianity by marching them through a river. Then, to promote a universal day for worship, he implemented a Sunday law in March, A.D. 321 as a political compromise. Constantine patronized everyone by declaring a weekly holy day/holiday. His Sunday law meshed with customary Roman practice and it aligned with the desires of the church at Rome. Even non-Christians were quite happy with a national day of rest. “Let all judges and all city people and all tradesmen, rest upon the venerable day of the Sun. But let those dwelling in the country freely and with full liberty attend to the culture of their fields; since it frequently happens, that no other day is so t for the sowing of grain, or the planting of vines; hence the favorable time should not be allowed to pass, lest the provision of heaven be lost.” (Cod. Justin, III Tit 12, L.3., March 7, A.D. 321) Did you notice that Constantine’s decree did not mandate worship on Sunday?


Although Christians in Rome had been meeting on Sunday for more than a century when Constantine announced his decree, other Christians around the Mediterranean Sea were not overjoyed. Most of the Christians outside Rome were still observing the seventh day Sabbath. Socrates writes near the turn of the fourth century: “Such is the difference in the churches on the subject of fasts. Nor is there less variation
in regard to religious assemblies. For although almost all churches through the world celebrate the sacred mysteries on the Sabbath of every week, yet the Christians of Rome and Alexandria have ceased to do this.” (Socrates, Ante-Nicean Christian Library/Ecclesiastical History, Book V, chap 22, Vol II, (Boston, 1887) p. 132)


Constantine’s decree did not abolish the importance of the seventh day Sabbath; something else would have to occur before that could be accomplished. The leaders from the church in Rome needed a doctrine that dealt directly with the “Lord’s Day” to present a strong case before a contentious and divided body of Christians. Eusebius, another apologist (peacemaker) of the era, was a Christian confidant and advisor of Constantine.
He masterminded a doctrine for Sunday observance that remains intact for Catholics today. Carefully notice his anti- Semitic argument for the observance of Sunday:
 
“Wherefore as they [the Jews] rejected it [the Sabbath law], the Word [Christ] by the new covenant, translated and transferred the feast of the Sabbath to the morning light, and gave us the symbol of true rest, viz. [in other words], the saving Lord’s day, the first [day] of light, in which the Savior of the world, after all his labors among men, obtained the victory over death, and passed the portals of heaven, having achieved a work superior to the six-days creation. On this day, which is the first [day] of light and of the true Sun, we assemble, after an interval of six days, and celebrate holy and spiritual Sabbaths, even all nations redeemed by Him throughout the world, and do those things according to the spiritual law, which were decreed for the priests to do on the Sabbath. And all things whatsoever that it was the duty to do on the Sabbath, these we have transferred to the Lord’s day, as more appropriately belong to it, because it has a precedence and is first in rank, and more honorable than the Jewish Sabbath. All things whatsoever that it was duty to do on the Sabbath, these we have transferred to the Lord’s Day.” (Eusebius’s Commentary on the Psalms, Psalm 92, quoted in The Literature of the Sabbath by Robert Cox, Vol I, p. 361, italics and insertions mine)

Did you notice the last two sentences in Eusebius’ argument? Eusebius testifies that “we” (Constantine and the leaders of the church) “have transferred all things, whatsoever that it was duty to do on the Sabbath” to Sunday. Eusebius offered no Scriptural authority for this change because there is none. Additionally, no church father or council from that time- period challenged or affirmed Eusebius’ claims. As it turned out, Eusebius took the thorny problem of worship in hand and became the father of a heresy that favored the apostate practices of the church in Rome. When a mere mortal, no matter how well-intentioned, declares by his own authority that the law of an eternal Almighty God is null and void, he is both delusional and evil.


Centuries later, the writings of Eusebius created a huge problem for Protestants. Catholics do not question the sacredness of Sunday because they believe the Church has the authority to change God’s laws. They believe Jesus gave this authority to Peter and his successors. (Matthew 16:19) On the other hand, Protestants have had to scramble for answers, because they insist their faith and doctrine is based solely on the Word of God, but there is no biblical support for their Sunday-keeping arguments. Even though their reasoning is different, Catholics and Protestants abolished the Sabbath and substituted Sunday in its place. Who has higher authority – the Creator or the created?

One man says, “Every day is holy, I worship God every day of the week.”
Another man says, “It does not matter which day we worship on as long as we worship God.” Such comments show no regard for the Creator’s authority. If Jesus were on Earth today, He would say of most Christians the same thing He said of the Jews, “They worship me in vain; their teachings are but rules taught by men.” (Matthew 15:9)

Argument 7 does not support the sacredness of Sunday. It does explain how apostasy overtook Christianity.

This is where I think I'm getting off topic but my question really comes down to, who or what is the house of Israel? Is it or are they strictly a direct descendent of Abraham or is it something more? John the Baptist spoke of this too in Matthew 3:8-9 when he told the Pharisees and Sadducees:

8 Therefore bear fruits worthy of repentance,
9 and do not think to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones.
NKJV

The way I understand the verses I've been referencing, it is possible that all believers are part of the family of Israel for we have been grafted to be partakers of the root (Jesus) and ergo, joint heirs with Christ.
"who or what is the house of Israel?"
That is a good question. The quote from Jeremiah, that is also quoted in Heb 8:8 says:
“The days will come, says the Lord, when I will establish a new covenant with the "house of Israel and with the house of Judah".

Some say this New Covenant was only made with the Jews (the house of Israel and the house of Judah) and not for gentiles. Others say that the Church is the new Israel and therefore includes gentiles.

However there is another way of understanding this that avoids these arguments.
Note that both of these quotes refer to the HOUSE of Israel and the HOUSE of Judah.
So, what, or who, is the house of Israel and the house of Judah?

I think the answer is the king.
In 2Sam 12:8 the Lord (via Nathan) says to David "I..... gave you the house of Israel and of Judah..."
The king represents in himself the house of Israel and the house of Judah.

Another example of the king personifying the whole house is given in Isaiah 7:13 where Isaiah calls king Ahaz the "house of David"

Now who became the King?
Who was promised the throne of David?
Answer: Jesus:
"He will be great, and will be called the Son of the Most High;
and the Lord God will give to him the throne of his father David,
and he will reign over the house of Jacob for ever
;
and of his kingdom there will be no end.”
(Lk 1:32-33).
the "house of Jacob" is Israel before it split into Israel and Judah.

Jesus is the New Covenant promised in Jeremiah; he embodies the Covenant in himself.
In Isaiah, God speaks about the coming Messiah in several "Servant" passages
Is 42:6-7 I have given you as a covenant to the people, a light to the nations, to open the eyes that are blind, to bring out the prisoners from the dungeon, from the prison those who sit in darkness. This is very similar to what Jesus says about himself in Lk 4:18

Is 49:8 I have kept you and given you as a covenant to the people,
The implications are that Jesus is a living embodiment of the Covenant

The Messiah is given as a Covenant to the people, an embodiment of the covenant. And note he is to be a "light to the nations". He is not just for the Jews.

The Mosaic/Sinai Covenant could be, and was, broken. But if Jesus is the embodiment of the Covenant it can never be broken. That is why it is an everlasting covenant .

God says to Ezekial (and note this is long after David is dead)
My servant David shall be king over them; and they shall all have one shepherd. They shall follow my ordinances and be careful to observe my statutes. They shall dwell in the land where your fathers dwelt that I gave to my servant Jacob; they and their children and their children’s children shall dwell there for ever; and David my servant shall be their prince for ever. I will make a covenant of peace with them; it shall be an everlasting covenant with them (Ez 37:24-26).

Anyone can come into this Covenant. Since the Covenant is Christ, if we are "in Christ", a phrase Paul used often, we are in the Covenant.
 
It was not a sign of their covenant, but set apart by God as a Holy day that God sanctified as all, Jew and Gentile, to keep in remembrance which is different from the other 9 commandments.
And the Lord said to Moses, “Say to the people of Israel, ‘You shall keep my sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the Lord, sanctify you. (Ex 31:12-13)

Therefore the people of Israel shall keep the sabbath, observing the sabbath throughout their generations, as a perpetual covenant. It is a sign for ever between me and the people of Israel... (Ex 31:16-17)
 
No complaint, I guess you don't see things the same, when I mentioned Hebrews 13:8, my way of thinking is that, the same God who spoke to Moses is the same for us today.

But as I pointed out God's nature does not change but his actions do. And just because he told Moses to do something that does not mean he told us to do it.
 
No one is saying God rested every 7th day, but that we are commanded to keep the 7th day Holy unto God in remembrance of His creation as He sanctified it as a Holy day as He is Holy.

Gen 2:3 And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

Exo 20:8 Remember the sabbath day, to keep it holy.
If God didn't rest every 7th day then why do we have to rest every 7th day?

And I have pointed out before God may have sanctified that particular 7th day but scripture does not say God sanctifies EVERY 7th day.
 
Then why does the Catholic Church have the ten commandments hanging on their wall if they are only for the Jews to follow.

Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.

Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

(I do not want to make this about a discussion of the laws so please keep this on topic)
I've never seen the Ten Commandments on the wall of a Catholic Church, inside or outside.
But they are in the Catechism. That is because they fulfill two purposes.

From the beginning God made certain moral laws that are applicable to all men in all times. We call them eternal moral laws.

Mankind knew these laws from the beginning because they were made known to him by his conscience. Thus Cain knew that he had done wrong when he murdered Abel. We believe that man can know something about God and his moral laws from our nature and our consciences.

As the psalmist says:
The heavens are telling the glory of God; and the firmament proclaims his handiwork. Day to day pours forth speech, and night to night declares knowledge. (Ps 19:1-2)

Paul says:
Ever since the creation of the world his invisible nature, namely, his eternal power and deity, has been clearly perceived in the things that have been made. So they are without excuse; for although they knew God they did not honour him as God or give thanks to him (Rom 1:20-21)

And
When Gentiles who have not the law do by nature what the law requires, they are a law to themselves, even though they do not have the law. They show that what the law requires is written on their hearts, while their conscience also bears witness and their conflicting thoughts accuse or perhaps excuse them (Rom 2:14-15)

Thus God’s eternal moral law already exists before man is created and is embedded in our hearts.

When God called the Israelites of Egypt he had to build them into a nation, a kingdom. He did this by means of a Covenant where he bound them to a set of laws, a code of law. This Covenant was accompanied by blessings for keeping the covenant and curses for breaking it. This was standard for Ancient Near East Covenants (ANE Covenants).

All these laws were written down and can be found particularly in Exodus and Leviticus or in Deuteronomy. The Book of the Law (which contained the Ten Commandments) was put on the outside of the Ark of the Covenant. The Ten Commandments were also written on stone, by God, and placed inside the Ark.

The Ten Commandments are a summary of the most important part of the Law. In the Sinai Covenant they summarise the Covenant Law, the breaking of which can trigger the Covenant curses. Since the Gentiles were never a part of the Sinai Covenant they had no part in the Covenant blessings or curses when the Israelites kept or broke them. The Ten Commandments were not applicable to them, or us, as a legal code.

The moral laws in them (and in other parts of the OT) are applicable to us and the Ten Commandments are a good summary of (most) of them.

The Catechism of the Council of Trent put is this way:
But, lest the people, aware of the abrogation of the Mosaic Law, may imagine that the precepts of the Decalogue are no longer obligatory, it should be taught that when God gave the Law to Moses, He did not so much establish a new code, as render more luminous that divine light by which the depraved morals and long continued perversity of man had at that time almost obscured. It is most certain that we are not bound to obey the Commandments because they were delivered by Moses, but because they are implanted in the hearts of all, and have been explained and confirmed by Christ our Lord.
Seventh day sabbath keeping is not a moral law.
 
Argument 7: Early Christian Believers Met on Sunday


Another argument used to affirm the sacredness of Sunday is created from “cherry picking” the writings of early church fathers such as Barnabas, Justin Martyr, Didache, Ignatius, Dionysius, Clement of Alexandria, and Tertullian. This argument maintains these writers affirmed that early Christians met on Sunday for worship. This approach to the problem of Sunday sacredness is a smoke screen to hide the fact that the New Testament says nothing about Sunday becoming a holy day. Everyone knows that if certain historical facts are kept from sight, people can twist them to create a skewed view of history and make it be whatever they want. However, when all of the historical facts are presented, they tell a very different story than what is often represented as history.


During the first century A.D., Christianity spread throughout the Roman Empire because of persecution. Christians were constantly on the move to escape capture, confiscation, punishment, and death. For a while, each Caesar seemed to be more intent on destroying Jews and Christians than his predecessor. Therefore, early Christians made theological compromises to survive. During the second century A.D., Judaism’s influence over Christianity in Italy had faded because three or four generations of Roman-born Christians had come and gone. Jerusalem was a non-important heap of ruins and Christians wanted their own religious identity – an identity that had nothing to do with the Jews.


To make matters worse, many Gentiles had “joined the church” and brought their peculiar religious baggage. Consequently, Christianity in Rome mutated into a Romanesque version, which was unlike Christianity in other parts of the world.


By A.D. 150, 120 years after Jesus ascended, Christians, in Rome, had found areas where compromise was possible with Mithraism. This led to theological ecumenism and apostasy. Many Christian denominations are participating in a similar process today and again, the result will be awful.

When Rome destroyed Jerusalem in A.D. 70, Christianity was deprived of its headquarters and “main office.” Each church quickly found itself alone and became its own authority in matters of faith and doctrine. Early Church history indicates that Christians adjusted beliefs and doctrines as needed, depending on location and leadership. During the last part of the second century A.D., Irenaeus, the Bishop of Lyons, located in what is now called France, became alarmed with
the heresies that had infiltrated the Christian movement. He was aware of how Christians in Rome had begun to meet on Sunday and abandoned the seventh day Sabbath, and he spoke against it. He wrote: “For He [Christ] did not make void, but fulfilled the law [Ten Commandments].” (Irenaeus, Ante-Nicean Christian Library/Against Heresies, Vol 1, (Boston, 1887) p. 471, insertions mine)


Tertullian, another early church father, wrote extensively concerning Christian doctrine. He, like Irenaeus, was alarmed at the practices of certain Christians, especially those in Rome. In regards to the seventh day Sabbath he wrote: “Thus


Christ did not at all rescind the Sabbath. He kept the law [Ten Commandments] thereof . . . He restored to the Sabbath the works for were proper for it.” (Tertullian, Ante-Nicean Christian Library/Book IV, Chap 12, Vol 3, (Boston, 1887)
p. 362, insertion mine)


Debate over Sunday observance grew in those early years because the church in Rome defended the practice. Bishop Archelaus responded to bishop Manes, saying: “Again as to the assertion that the [seventh day] Sabbath has been abolished we deny that He [Christ] has abolished it plainly. For He Himself was also Lord of the Sabbath.” (Archelaus, Ante-Nicean Christian Library/The Disputation with Manes, Vol 4, (Boston, 1887) p. 217, insertions mine)


By A.D. 320, confusion and compromise had devastated many early Christian beliefs. Christians in Alexandria, Egypt were defending views on the deity of Jesus that opposed the church in Rome. The Christian leaders discussed, debated, and argued the need for centralized church authority and leadership. Many agreed that church doctrine needed to be de ned and protected so that heresy would not destroy Christianity, but they could not agree on a process or who would do the job best.


Poor communication, distance, differences in culture, education, language, and social factors began to define Christianity according to geography. It was easy to see the result would be a highly fractured church. Both the world and Christianity needed a strong unifying leader and Constantine concluded he was “the chosen one!” He believed God had divinely appointed him to rescue a crumbling Roman empire and the universal Christian Church. When Constantine ascended to the throne as sole ruler of the empire, about A.D. 312, he had transformed himself into a Christian for political advantage. Constantine was clever and saw Christianity as
a means of unifying an ethnically and religiously diverse empire. When he endorsed the version of Christianity that was centered in Rome, he set a sequence of events in motion that could not have been imagined.


To put the empire on notice that Constantine had established a new world order, he had his army baptized into Christianity by marching them through a river. Then, to promote a universal day for worship, he implemented a Sunday law in March, A.D. 321 as a political compromise. Constantine patronized everyone by declaring a weekly holy day/holiday. His Sunday law meshed with customary Roman practice and it aligned with the desires of the church at Rome. Even non-Christians were quite happy with a national day of rest. “Let all judges and all city people and all tradesmen, rest upon the venerable day of the Sun. But let those dwelling in the country freely and with full liberty attend to the culture of their fields; since it frequently happens, that no other day is so t for the sowing of grain, or the planting of vines; hence the favorable time should not be allowed to pass, lest the provision of heaven be lost.” (Cod. Justin, III Tit 12, L.3., March 7, A.D. 321) Did you notice that Constantine’s decree did not mandate worship on Sunday?


Although Christians in Rome had been meeting on Sunday for more than a century when Constantine announced his decree, other Christians around the Mediterranean Sea were not overjoyed. Most of the Christians outside Rome were still observing the seventh day Sabbath. Socrates writes near the turn of the fourth century: “Such is the difference in the churches on the subject of fasts. Nor is there less variation
in regard to religious assemblies. For although almost all churches through the world celebrate the sacred mysteries on the Sabbath of every week, yet the Christians of Rome and Alexandria have ceased to do this.” (Socrates, Ante-Nicean Christian Library/Ecclesiastical History, Book V, chap 22, Vol II, (Boston, 1887) p. 132)


Constantine’s decree did not abolish the importance of the seventh day Sabbath; something else would have to occur before that could be accomplished. The leaders from the church in Rome needed a doctrine that dealt directly with the “Lord’s Day” to present a strong case before a contentious and divided body of Christians. Eusebius, another apologist (peacemaker) of the era, was a Christian confidant and advisor of Constantine.
He masterminded a doctrine for Sunday observance that remains intact for Catholics today. Carefully notice his anti- Semitic argument for the observance of Sunday:

I find this a very hypocritical argument.
You want to dismiss all the quotations from the early fathers that support an early transition to Sunday worship as "cherry picking", and then go on to "cherry pick" quotations yourself.

And much of it is also opinions unsupported by any evidence.

As such it is worthless.
