The "Word" referenced in John 1 is Jesus a person, not a written record. Thus, this point of yours is meaningless.
Where in
Luke 16:19-21 Is God revealing anything to Lazarus?
Romans 11:24, this references what happened after the Law came into existence, Paul was born under the Law and thus cannot be speaking of his own experience.
Paul never states that he did not meet Jesus face to face, merely that he never followed Jesus before his conversion. It is hard to believe that he had rabbinic training, as he claims, and did not at least see Jesus on occasion. I have seen many political and/or religious leaders that I never followed.
As for Paul writing, he admits to writing his own name 5 times, and makes note that his readers can know because it was him because the letters were so large. Remember, paper was expensive, ink was expensive, having someone deliver and read the letters so that others who could not read would get the message was expensive. Are you suggesting that Paul had so much money to waste that he wrote the letters when his writing was unusually large as opposed to using a scribe who was trained to get the most words on a page of paper, adjusting what was dictated, when necessary, just as a good secretary does for their boss?
