Good point.  Many people do not realize that the Magisterium existed from the very beginning of the church, as did the latin mass, vestments, gregorian chants and all the things the restorationists revere.  Some heretics would even go so far as to suggest that many of these things were developed hundreds of years after the Pope Peter died, and were merely man-made innovations of their time.

But I am troubled by your suggestion that corruption is a 1900 year old tradition of Holy Mother Church.
