Alright, I just noticed that you are Orthodox and not Catholic. My apologies for the mistake. So, the amendment is that my latter comments are really directed to Roman Catholics and not the Orthodox. The underlying principle is the same. The fact that we do not have a man-led centralized power structure, whether iron-fisted or less so, does not make us responsible for people going off into crazy cults. The exact same thing has happened under Protestantism, Catholicism, and Orthodoxy from the beginning. Forgetting about the original Protestants, there is a long list of groups that broke away, practically RIGHT AWAY.
Maybe that's why the authority, especially in the RCC, tightened after a time, and kept tightening. However, it seems to me that this would be admitting a failure in God's original set up and system.
