It’s a matter of progressive revelation. That Christ did or did not claim is an invalid argument in and of itself. The fact that Christ told us that the Law and Prophets testify about Him places the demand on us to find Him there.
We progressed from Jesus, to Paul, to Mohammed, to Joseph Smith, to the Jehovah Witness program and a whole bunch more mixed in. Like Benny Hinn and Oral Roberts and Jimmy Swaggart, and Copeland, Cefro Dollar. All this progressive revelation that left Jesus in the dust is confusing to say the least. That is if you give them any credence.
Paul was the first one of record that progressed. You know, he talked to Jesus and got the OK to progress.
