Point being is that no food is forbidden to us now. Of course, that does that mean we have to eat everything in sight. Some things we are better not consuming. The prohibition of certain foods in the Hebrews diet and the wearing of certain types clothing along with trimming of the beards, tattoos, etc were binding upon the nation of Israel to separate them from the other nations surrounding them that were evil. However, homosexuality is a moral law that was not abolished in the New Testament. It is binding upon us now. All of the moral commandments of the Mosaic law are still in force today; do not take the Lord's name in vain, do not kill, do not steal, do not commit adultery, etc (Exodus 20).
So when someone wants to say that since Christians always want to condemn homosexuality and those same people want to argue that the Old Testament law condemns the wearing of different fabrics, or say you cannot eat shellfish or shrimp, kindly explain to them what laws are binding upon us now, and which ones are not binding.
God's moral law always applies to us. God's customary laws do not apply because those laws have been abolished with the ushering in of the New Covenant.
