Perry,
While you complain about the way that the Watchtower modifies the text of the Bible to suit its own beliefs, this is exactly what the NT writers also did when they referenced their own religious writings. There was no canon of Hebrew Scriptures at the time (hence the many times they cited texts such as 1 Enoch).
When you look at "heresies" (opinions) through the eyes of the Church Fathers, you are reading only their opinions. One person's "orthodoxy" is another person's "heresy".
It is simply an accident of history that the Paulines became the state religion and were thus able to determine that their writings would form Scripture. The bulk of the NT is made up of wriitngs by Paul, by people who pretended to be Paul, and by people who supported Paul. Little survives from the supporters of the Jerusalem Church (such as Matthew and James). Although Peter was a leader at Jerusalem, little is known of him, while 1 Peter and 2 Peter were written by Paulines decades after Peter's death. Likewise, the Gospels were written many decades after the events they describe, and some owe their thoughts to Paul.
