I always loved reading the writings of Paul. They always seemed so logical and interesting. Now, I have to ask myself, "Was he really any different than Rutherford?" After all, he inserted his own thoughts into the mix, by his own admission. Then he would say, "Not I, but the Lord!"
One crazy person begets another crazy person I guess. I think I would be slightly more impressed if Jesus had written his own books or letters and not left the whole thing to anonymous authors (the Gospels) or to Paul who never met Jesus except in a vision. I think it was Hume that pointed out revelation is necessarily first person and to everyone else it's hearsay.
If you accept the words of Paul then one also has to accept the words of Muhammad and Joseph Smith.
