That is my belief. They where still in the Old Testament until Jesus was put on the alter. I don't believe you will find many who will disagree with that even in the Church of Christ. He could not baptized in the name of the Trinity until the Coruscation, the way I see it.
Following your train of thought, then even if Jesus did baptize the Apostles (pre-resurrection), it wouldn’t have been sufficient to add them to the Church.
I see your logic. I can’t say I agree with your premise.
