And so you can not rightly claim the Gospels contain the "words of Christ "can you? Just as the words in the gospel are inspired so are the words of Paul
They are the words of Christ as far as the Church teaches. If you would reduce the Gospels to less than those of the Pauline epistles (quick now - how many of the Pauline epistles were actually written by Paul?) then you really don't have any claim to call yourself Christian, do you?
