Christ did not write down anything, despite the fact that he was highly literate.

He did not "build" Temples and Churches, He did not create a "written code".

The great secrets about and around the Life of Jesus was too much to bear, soon people were building Churches and doing the same things Jesus advised not to do.

Every institution built by man is flawed, the best we can hope for is that they serve their purpose - more or less.

The Roman Catholic Church is one of those institutions plenty flawed.
