My point is more general. You should not assume that everything is in the Bible. You are not a Muslim and Bible is not Koran.
The Church is not based on the Bible but Bible is based on the Church. Old Testament was written by the Church ie by the Jews. New Testament was written by the New Church - early Christians. But not everything is included there - for example "there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written."(Jn:21:25)
