Oops for some reason I misread your post. You might not be well versed in history but before the Reformation Christianity in the West ,with the exception of sects that even modern day Protestants would call heretical, was Catholic under the See of Rome. It was indeed unified.
Unless you are confusing different schools of theology and their disagreements with dogma that has been settled and is binding on all Catholic faithful. Or do you mean the numerous religious orders found in Catholicism?
Dear lastchance,
I understand that Bullwinkle J. Moose has retired from his position of being “Mr. Know-It-All”
You should consider sending in your application for the job, you certainly are qualified.
