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.
Which is contained exclusively in scripture. Catholics, Mormons, and Muslims put their faith in the writings of fallible men.
>>“Go forth and TEACH...,” both His written and unwritten words.<<
No where in scripture did He say to teach "unwritten words" other than what the apostles taught. The only infallible source we have for what He and the apostles taught is scripture. Anyone gullible enough to believe that word of mouth hasn't changed in 2000 years is head in sand stupid.
