I don't disagree with you but Peter and the rest they never disappered they were busy also, with the Gospel.Remember when Paul was striked by lightining and when he changed he had to meet with them. Mathew, Luke, John and Mark have not beeen written by Paul, Hebrews, Acts, John, Peter, James and Revelation were not written by Paul, even Jude. I'm not sure about Romans.Most books he influenced and I think its not over 90% every disciple of Christ is the Greatest Christian in the Bible. becuase Saul was pesecuting Peter and the rest and that is when He met God and changed to Paul.
Hope is not a strategy
