Are you seriously claiming that any of the Apostles were alive in 150 AD?
And no, you are wrong. The 4 gospels were written while witnesses of Jesus and his ministry were still around to talk about it. Most of the letters to the churches were written by the Apostles or people anointed by them in the first 5 - 10 years.

What churches??anointed?? None of the writings were acknowledge by anyone except by emperor Constantine until
300 AD and no they were not written by the apostles. Read what the bible says. The book according to John or who ever. According to, that mean he did not write it. It is a retold story.
