Not deriding Adam, that is just silly. Adam was not a begotten son of God, was he. He was however created in the image of God without sin. Until....he willingly disobeyed God.
Adam was God's son, beyond any doubt. But I wouldn't go as far as making Adam sinless at any point.
The distinction of Jesus, as a man, is to have had His Body Fathered by God, through the Holy Ghost, not "formed" from dust as Adam was. God via His Spirit inserted or Fathered Himself into what He originally formed/created. It's an interesting set of contemplations to say the least.
Matthew 1:18
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
It's impossible to say Jesus was not a human being in every way but ONE, that being without sin. This also shows sin as a matter not necessarily human, which I touched on earlier. We should not presume that the human nature is the only nature involved with sin. It's not. Sin is a matter of adverse spiritual nature, which ALL have been made 'subject to.' I'm a minor expert on 'subject to' clauses as it is commonly used in the legal contracts I spent my working life being involved with.
God made man subject to the spirit of disobedience in the flesh. God did NOT make His Own Body "subject to" the spirit of disobedience.
Therein is the unique difference between Jesus as a human being and all other human beings.
Do you agree with Federal Headship in the family? That the father is responsible for the condition of his family.
If we pay attention to the details, God is NOT the Father of the spirit of disobedience. When various theological concepts come down the turnpike, such as "Federal Headship," they always tend to one sided non-encompassing sights. They make for great crowd sourcing of various ideas but theology is a tad bit more complicated.
IF we examine the construct of man, we should be seeing man and also the spirit of disobedience in the flesh of man. Therefore there are technically two separate parties involved. And God does have TWO entirely different relationships going on, SIMULTANEOUSLY.
For example, God is simultaneously for and in behalf of good, (the persons) and simultaneously against evil, (the spirit of disobedience.)
Both sights are fixed, immovable, in and by Gods Eyes.
The Federal Headship concept would do itself much better to recognize these distinctions. It becomes even more problematic when we get into the arena of theodicy. God's uses of evil in behalf of people (so that we would understand and partake in GRACE, MERCY and HOPE.) And again we'd have to have the two basic sights above still in mind. IN other words grace, mercy and hope are for humans, but NOT for the spirit of disobedience.
Everytime we make a theological posture, we have to have a full accounting for the opposite sights involved with the spirit of disobedience. Even though this seems rather simple/easy, it's really not.
In Christian theology concepts we are always dealing, simultaneously, with positive and negative aspects. The negative is too often overlooked and disregarded. And even further, if we understand "how" the negative aspects work, that's part of the very real working of the negative. It wants to and is compelled to deny both sides of the ledgers and only lean to one side, including itself, the spirit of disobedience, in the positive. That can't happen in truthful Christian theology.
Paul explains it when he sites what an elder in the church should be.
Adam blow it and sin entered the world through him, not through Eve.
We maybe should recognize that Eve was already "in Adam" from the moment they were created.
Genesis 5:2
Male and female created he them; and
blessed them,
and called their name Adam, in the day when they were created.
We have no record of "blessings" given directly to Eve, post separation or forming by God. She was blessed while "in Adam." Women are technically a picture of our respective "inner man." God created an outer man, a natural man, Adam, and simultaneously an inner man, Eve. This is partly why the "church" is termed a 'woman.'
Jesus is only interested in the "inner man." Not the natural or outer man.
And additionally, IF we pay attentions to the details, the WOMAN is taken out of the man after the deployment of THE LAW, do not eat. This is a reflection of Gods Order. A natural man is formed first. Then comes Gods Words. The natural man doesn't understand, is "asleep and in darkness" resulting from said Word. And an "inner man" is then formed. 1 Cor. 15:46.
And Jesus Himself complied to the same principle. He was first, as a human, a natural man who passed away in death. Just like we do.
Righteousness entered the world through the Christ as the Second Adam and He overcame, He won the victory over sin and death.
This is what we do know for sure......
The Victory was always and only to be had and held by God Himself, in Christ. There can only be One Truthful Victor. God Himself. Who would want it any other way anyway?
IF we can't trust Eternal Perfection who can we trust? :yes
Rom 5:12 because of this, even as through one man the sin did enter into the world, and through the sin the death; and thus to all men the death did pass through, for that all did sin;
Eve was in transgression first but that did not bring sin into the world.
Sin is a direct result of the spirit of disobedience that is NOT man. See Mark 4:15 and 1 John 3:8 for example of the principle and the outcome that is involved with sin. Sin is a demonic matter, so we have to get the devil into the picture of fact. And the devil will resist that from happening, and will instead try to blame only Adam/Eve or humans only.
That's how the devil rolls.
Heb 7:9 and so to speak, through Abraham even Levi who is receiving tithes, hath paid tithes,
Heb 7:10 for he was yet in the loins of the father when Melchisedek met him.
Not in the loins of his mother.
There are no humans who are not direct decedents of both Adam and Eve.
Jesus was not begotten by an earthly father
That's not entirely true, above. Yes, Jesus DID have earthly progenitors of His Body, fathers if you will, or the body of Mary would have not been there to give birth to Jesus. We can't remove "man" in the earth body fathers senses from the Body of Jesus, even though Jesus Himself was birthed by God, through the Holy Ghost.
and was born without the original sin.
See above about the "spirit of disobedience." No, Jesus did not have that issue.
When we talk about "original sin" it is or at least should be a discussion of the devil, not of man.
When you listed all of the line of Mary, each one of the men in the line were begotten by an earthly father and was born with the original sin.
Well of course there are many MEN in the lineage of Mary, which is directly reflected into the Body of Jesus. He Himself was "born of a woman," an inner man.
