So there was nothing wrong for those in the NT to make circumcision a religious practice?
1) to avoid being ruled by church leaders, the way Moses entered into God´s 1st covenat.
2) to avoid being touched by any other man, and without anesthesia.
But that would not add anything new or needed, except that a new man-made rule (just for me)
Joh 7:22 Moses commanded you to circumcise your sons. But it wasn't really Moses who gave you this command. It was your ancestors, and even on the Sabbath you circumcise your sons
Act 7:8 God said to Abraham, "Every son in each family must be circumcised to show that you have kept your agreement with me." So when Isaac was eight days old, Abraham circumcised him. Later, Isaac circumcised his son Jacob, and Jacob circumcised his twelve sons.
Exo 4:24 One night while Moses was in camp, the LORD was about to kill him.
Exo 4:25 But Zipporah circumcised her son with a flint knife. She touched his legs with the skin she had cut off and said, "My dear son, this blood will protect you."
Exo 4:26 So the LORD did not harm Moses. Then Zipporah said, "Yes, my dear, you are safe because of this circumcision."
