What Was the Doctrinal Development of the Church in the Forties?

Paul didn't seem to be a theologian, so he may not have been sensitive to a good bit of the doctrinal development that would be certain to happen in a two thousand year period. Paul reported going to mass on christmas eve, and he reports it as if it were a normal thing to do. The niebelwerk gave them direct sensory experience of a great mystery that's at the base of reality. And even though they could now sense it, they realized that it's beyond the capacity of our finite minds to comprehend.
