Right. He's GOD. Why do we put such restraints on him? sigh.......
And the Bible itself has undergone compilation changes many times. The Shepherd of Hermas used to be considered canonical. The Roman Catholics use a different compilation than do the Protestants. The Bible itself references several books it does not contain and for which no manuscripts have been found.
Early church fathers wrote of biblical books and apostolic letters that were being changed or even fabricated by Gnostics, Marcionites, and other heretical groups in order to support their teachings. The Gnostics used a book called The Secret Gospel of Mark to support the contention that Jesus was homosexual (you can see that argument is as old as Christianity itself). Clement of Alexandria addressed this charge by stating that he was aware of the book, that it was canonical, and that it did not say what the gnostics claimed it did. Yet we have no manuscript at all from the book save a small snippet Clement includes in his letter regarding the controversial passage.
