Paul and the 12 were not one Church?
Then is Christ divided? (1 Corinthians 1:13)
We know the Church is Christ's body. (1 Corinthians 12:27)
And that Christ's body is one. (Romans 12:5)
And that in Christ, their is neither Jew nor gentile. (Galatians 3:28)
So why do you claim Christ's body (the Church) is not one?
I ask again: Is Christ divided?
No, Christ is not divided, But He does have a TWO-FOLD plan that has not yet been joined into ONE.
Eph 1:10 (AKJV/PCE)
(1:10) That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; [even] in him:
I understand that an fully indoctrinated "Catholic" like yourself has a terribly hard time with what the scripture actually teaches, but that's just too bad.
Why do you suppose that Christ taught the TWELVE apostles that they would judge the TWELVE tribes of Israel? Did Christ not know about Galatians 3:28? (Yes, I'm aware that He knows all things).
The RCC tries to steal Israel's place in the world. But God is NOT currently working on that part of His plans. He is currently building a body of believers that are seated in heavenly place and that are not under the Law as was Israel in its earthly kingdom.
