The OP was "Do Christians Keep the Mosaic Law?"
IMO no...but we do keep the Law of the Spirit of life in Christ Jesus
Romans 8:1-4
8 There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. [sup]2[/sup]For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. [sup]3 [/sup]For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, [sup]4[/sup]that the righteous requirement of the law might be fulfilled in us who do not walk according to the flesh but according to the Spirit.
...which Jesus explains in Matthew 22:37-40.
[sup]7 [/sup]Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ [sup]38[/sup]This is the first and great commandment.[sup]39 [/sup]And the second is like it: ‘You shall love your neighbor as yourself.’ [sup]40 [/sup]On these two commandments hang all the Law and the Prophets.”
The first commandment speaks of our covenant relationship toward God.
The second encompasses the rest of the nine commandments -
Romans 13:9-10.
[sup]9 [/sup]For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not bear false witness,”“You shall not covet,” and if there is any other commandment, are all summed up in this saying, namely, “You shall love your neighbor as yourself.”[sup]10 [/sup]Love does no harm to a neighbor; therefore love is the fulfillment of the law.
Therefore, love is the fulfillment of the law [of the Spirit]
Why do I believe that we do not keep the Mosaic law even though the Law of the Spirit seems to encompass the same law? ...because it could not be kept under the old covenant.
Romans 3:20
[sup]20 [/sup]Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.
However, the bible says that the law is established by faith in Jesus Christ.
Romans 3
[sup]26 [/sup]to demonstrate at the present time His righteousness, that He might be just and the justifier of the one who has faith in Jesus.
[sup]27 [/sup]Where is boasting then? It is excluded. By what law? Of works? No, but by the law of faith. [sup]28 [/sup]Therefore we conclude that a man is justified by faith apart from the deeds of the law.
[sup]31[/sup]Do we then make void the law through faith? Certainly not! On the contrary, we establish the law.
So again, faith is also a fulfillment of the law [of the Spirit].
Blessings!!!
