Your entire post was excellent, but the part above was outstanding!
The author's ENTIRE thesis is that, "if it sounds Catholic" it's automatically heresy and this seems to based upon a predetermined conclusion that Catholicism is heresy. It really is the most intellectually hollow thesis someone can ever have.
Very well summarized wagglebee, thanks!
The author is judging the Fathers by his own theological standards. That's a fair theological position. It's a horrible *historical* position though. If these beliefs were heresy, why were they never corrected by later Fathers, Fathers who were happy to correct people like Origen or Tertullian on other matters. If they were out of the mainstream of Christian thought, why didn't mainstream Christian thought repudiate them as it repudiated Cerinthus and Arius and everyone else?
The simpler historical explanation is that the Fathers weren't the heretics. Way of Life are the heretics. ;)
