I am sure that you and I do not disagree here.And now a series of questions:
Do JWs believe that circumcision was ever required of God's people?
Do JWs believe that circumcision is now required of God's people?
If the answer is not the same to both questions, please, account for the change.
Circumcision was once required for God's people from the time of Abraham. This requirement was later included as part of the Law of Moses. But after Jesus provided the ransom sacrifice, Christians were no longer obligated to follow the Law of Moses or be circumcised. However, on one occasion Paul circumcised Timothy, not because it was a requirement of God, but in order not to offend the Jews that they were preaching among.
Circumcision was once required. But according to the Bble, now it is not required. Nevertheless Muslims, of course, still hold circumcision to be a requirement.
