The apostle Paul taught that we are no longer under the Law. Period.
The verses are Leviticus 18:22 and 20:13. First, Thou shalt not lie with a man, as with a woman: it is abomination. Second, If a man lie with a man, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
There is, however, a big problem with quoting Leviticus. The problem is that Christians are no longer under the Law. We do not live our Christian life by following the Old Testament Law. The Apostle Paul makes this abundantly clear. It is not something fabricated to win an argument, or made up in the twentieth century, or manufactured to get around something somebody doesnt like. It is clearly stated in the Greek scriptures. The Apostle Paul wrote it in Galatians:
All who rely on observing the law are under a curse, for it is written: Cursed is everyone who does not continue to do everything written in the Book of the Law. (Galatians 3:10)
If we rely on following the Law (the Torah, the first five books of the Bible) we are under a curse. The passage above, Galatians 3:10, contains a quote from the Law itself, Deuteronomy 27:26. According to Pauls statement below, things have changed.
Christ redeemed us from the curse of the Law by becoming a curse for us. (Galatians 3:13)
It was Jesus death on the cross that rescued us from the curse of the Law. If we insist on following the Law and imposing the Law on others, we negate the cross of Christ, and repudiate Christs death on the cross.
