Well that's at least a concrete date. But I am not going to settle for vague accusations of progressive corruption.
Hippolytus of Rome...died around 235. Was he orthodox or heterodox? If heterodox, then why? How about Pope Cornelius (251-253)? Cornelius was friends with Cyprian, bishop of Carthage. Was Carthage being corrupted too around that time?
Can you show me someone on either side of your cutoff, and tell me what the person pre-200 believed that the person in, say, 400 or 500 didn't?
Or can you point me to someone in the 200s or 300s in Antioch or Alexandria, or Byzantium, or Gaul who remarked on Rome's gradual apostasy? There were churches all over the place outside Rome...surely someone noticed and complained, right? Chrysostom in Constantinople? Jerome in Jerusalem? Augustine in Hippo? Ambrose in Milan?
Show me one ancient author who wrote about this alleged Roman apostasy when it was happening.
Jesus Christ Himself pointed it out. In Revelation He spoke to the Seven Churches and pointed out their errors. Roman Catholics would claim those churches as catholic....
I can show you one aspect of how Rome apostasized.

To respect the Religion Forum Rules, allow this general statement to serve as a response...
• Those who have eyes open to the truth and seek it, will find it.
• Those who are willfully blind to truth, neither treasure it, nor seek it.
• Those who blindly accept their own religious traditions, without verifying their source, have predecided truth is not a primary pursuit.
• Those who demand others spoon-feed them, have already decided to spit it out and complain it isn’t real food.
