PLEASE use facts, as listed in the Bible timeline. All of the books used in the Bible are Holy Spirit inspired, the real author.
Point being... If we are going to claim that the 4 Gospels, though written by others, from memories, years later, or that the Old Testament or any of the other writers of the NT were inspired by the Holy Spirit, we have to give Pauls writing the same authority, as it was written by the same inspiration of the same Holy Spirit.
