Christ did after all say He came for the most elite and sophisticated among us didn't He. Oh,,,,,,,,,,wait.......
No. But He wanted to be sure that He taught ONE truth and gave Peter and his successors an unbounded authority, that ‘WHATSOEVER.... bound on earth shall be bound in heaven...”
This is why Christ commanded his apostles to “Go forth and TEACH...,” both His written and unwritten words.
To make sure this teaching is HIS teaching is why we have theologians. Not the teaching of Joel Osteen; Billy Graham, or David Koresh, or Jim Jones.
