I've heard countless criticisms to Christianity, many very rational and elaborate, and though I once agreed with these criticisms, I now find that these problems can all be solved by Orthodoxy and addressed in the following three categories:
Proactive Reasoning: What Is True?
Why Empiricism is insufficient
Why Hyper-Rationalism is humanistic and rejects fallen nature
Why rational holy spirit guided traditional authority is true
History of Christian epistemics.
Everyone of every denomination trusts the Orthodox Church that they kept scripture intact, which is rooted in their apostolic continuity.
