I thought that the apostle Paul even after his conversion continued to honor the Sabbath , Passover etc. I have friends who are born again Christians that recently through blood tests discovered that they were Jews. Now they wont eat pork or certain seafoods. Could you clarify this better. If you are a Jewish Christian do you have to live in both worlds?
Paul said,
“Though I am free and belong to no man, I make myself a slave to everyone, to win as many as possible. To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), so as to win those under the law. To those not having the law I became like one not having the law (though I am not free from God’s law but am under Christ’s law), so as to win those not having the law. To the weak I became weak, to win the weak. I have become all things to all men so that by all possible means I might save some. I do all this for the sake of the gospel, that I may share in its blessings.” (1 Cor. 9:19-23)
When he was around Jews he acted like a Jew. When he was around Gentiles he acted like a Gentile. He did this so as not to offend anyone, not because he was bound to the Law. He knew that in Christ there is neither Jew nor Gentile (Gal. 3:28). Every one who is born again is part of the Church regardless of their heritage. There is no standard for Jews that’s different than for Gentiles.
