That was when the New Testament was compiled. Not re-written. There is a difference. Some of the Epistles didn’t make the cut. I assume they did a lot of praying to decide what was divinely inspired and what was not. There are some pretty dire warnings in Revelation about taking away or adding to the book.
-- In addition to Matthew, Mark, Luke, and John, there were other stories of the life of Jesus.
Yes there were. However most of those were written after the Gospels and were not considered as either inspired or very authentic.
-- Jesus married and had children.
No, he didn't. Sorry. There is no evidence of this claim.
-- There were more than 12 Apostles, and some were women.
Of course, there were more then 12 Apostles. There were Matthias, Barnabas and Paul to name three. There were 12 chosen before His death though. The Bible is clear on that point. The others became apostles later. Were some women? Not real likely but slightly possible. Philip the evangelist had four daughters who prophesied so there were women in at least minor positions in the Church. In fact according to 1 Corinthians 12 prophets came right after apostles in the church hierarchy.
(And because of that last part I am bound to get flamed.)
