neither do I. I do know that there were a whole slew of Gospels back in the day. The church (I am assuming the early Roman Church) edited down the Gospels to only those by the 4. I read there was a Gospel of Judas, if you can believe that.
I don't know what is the true bible. I believe Jesus is the messiah...I follow his moral teachings...after that I just don't know.
There are a lot of things I don't 'know' either.
Since what I 'know' about Jesus COMES from the book these early church folks assembled from various writings, and what I 'believe' about Him also comes from the same book, I must, to be consistant, also 'believe' whatever else I find there.
True, there are many things that seem to require 'interpretation', but study of the subject can move many from the Belief column to the Knowledge column.
