I am with Tony on this circumcision and non circumcision, Bride and Body thing. We may see it a little different I don't know? All of the apostles taught New Covenant teaching. It is only in two or three of Paul's writings that this isn't the case. If you read all of the epistles with this thought in mind you can see the difference. Always ask yourself, who is it addressed to. Who, what, where, when, is the key. I do believe most of the epistles were to the Israelites, that is who Jesus told them to go to.
