Still, Christians follow OT laws like the 10 commandments. Also, this sounds like that statement contradicted what g-d originally said about eating unclean food. It's either you can or you can't.Acts 10: 9-16
9 The next day at about the sixth hour, as the men were approaching the city on their journey, Peter went up on the roofto pray. 10 He became hungry and wanted something to eat, but while the meal was being prepared, he fell into a trance.11 He saw heaven open and something like a large sheet being let down to earth by its four corners. 12It contained all kinds of four-footed animals and reptiles of the earth, as well as birds of the air. 13Then a voice said to him: “Get up,Peter, kill and eat!14“No, Lord! Peter answered. “ I have never eaten anything impure or unclean.15 The voice spoke to him a second time: “ Do not call anything impure that God has made clean.16 This happened three times, and all at once the sheet was taken back up into heaven.
God, not Paul abolished that in the New Testament. Christians believe in the new Testament which abolished the law of the Old Testament.
