Socratic logic argues you must first agree on the meaning of terms and definitions. Next is determination of what the facts are. Lastly is logical arguments. Guess which part is the most difficult?
Religious logic is like this. It presupposes a greater mystery that has been partially revealed to us. It also presupposes that our fallible logic cannot on its own understand the truth. In other words it defines faith as believing in the greater truth even if the world and every one says we are foolish to believe in such fairy tales.
