No, that's a really stupid comment.
You are failing to understand Covenants and Covenant Law.
I wrote this in another thread on this topic
Some points to consider.
1. There are different categories of laws - moral, ceremonial, societal, and whether they apply to a particular person depends on the category and addressee.
2. I believe that there is an eternal moral law that mankind can know and is subject to. These are moral imperatives that are applicable to all peoples in all places throughout all time. These laws are written on our hearts and made known to us by our consciences (see
Rom 1:19 &
2:14-15).
A good example of this is the murder of another human being. This was wrong from the beginning. We know this because God condemned Cain for murdering Abel, and Cain knew he had done wrong. (
Gen 4:8-12)
God specifically told Noah If anyone sheds the blood of man, by man shall his blood be shed; For in the image of God has man been made. (
Gen 9:6).
God specifically put this law into the covenant law that he gave to the Israelites on Sinai (
Ex 20:13). When that law was abrogated this did not make murder OK, the eternal moral law remains. Moreover we can find this command re-iterated in the New Covenant that is applicable to Christians. (e.g.
Mt 15:19,
1Tim 1:9,
1Jn 3:15).
It not so much that murder is wrong because it is in the Ten Commandments, but that it is in the Ten Commandments because it is wrong.
Every countries legal code has a law against murder. But a countries legal code is only applicable to those under its jurisdiction. Similarly the legal code that is the Ten Commandments was only applicable to those under its jurisdiction – namely Jews or those living under their land (their jurisdiction).
3. Sabbath keeping is a ceremonial law given to the Israelites; an important one because it is the sign of the their Covenant. But is was only applicable to those living under that covenant, or those gentiles living with them.
4. An understanding of Covenants is very important. From the very beginning God has dealt with mankind with a series of covenants - even with Adam (
Hosea 6:7).
The Sinai (Mosaic) Covenant was a temporary covenant. I has been superseded by the New Covenant.
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)
5. Apart from the eternal moral laws, the laws for one covenant do not apply to another one (thought they may have similar laws). You need to understand which Covenant belong to in order to know which laws apply to you.
.I am a UK citizen and UK laws apply to me. But if I travels to the USA then USA laws apply to me as long as I am staying in the US.
Similarly I live under the New Covenant and not the Old Covenant. The old Covenant laws do not apply to me. The eternal moral laws apply to me, but not the ceremonial laws in the Old Covenant (e.g. sabbath keeping).
