It is clear to me you are neither conversant with Ecclesiastical History or, generally, the history of Christianity and its Doctrines and orthopraxis.
Do yourself a favor and go to out www.newadvent.com and check out the writings of the early church fathers.
Have a productive Advent and a Blessed Christmas, brother
Didn't Christ come and overturn the established order the way he overturned the tables of the moneylenders outside the temple?
I'll ask for you to do yourself a favor and scrap Ecclesiastical History, Doctrines, and Orthopraxis for the words of Christ themselves as recorded in 4 Gospels and through the works of Paul.
Neither the People of the Way of the 1st century nor Christ Himself would recognize the bloated hierarchical mess that purports itself to be the true Church....
Final thought-- being born a catholic is a cultural distinction. The nation of Christ, however, is made up of those who step outside their cultural backgrounds and are second born as children of the Living God.
I'm sure you know this, and I've no doubt that you're a committed Christian. But at a certain point those who proclaim Christ as the central authority of their lives need to let go of "Ecclesiastical History"
and begin listening to the promptings of the Holy Spirit.
For the believer, every day is now advent. Good luck.
