It's a big subject which is difficult to do the proper justice in the space of one column. I expect the comments will be along the lines of, "You don't truly understand X," and, "On the contrary, it is you who doesn't truly understand X or Y."
Very few Catholics are aware that we are doctrinally bound to believe that the existence of God can be proven with certainty with unaided human reason. From her canons:
1. If anyone says that the one, true God, our creator and lord, cannot be known with certainty from the things that have been made, by the natural light of human reason: let him be anathema.Of course this does not mean we are capable of attaining perfect knowledge of God on our own power:
If anyone says that in divine revelation there are contained no true mysteries properly so-called, but that all the dogmas of the faith can be understood and demonstrated by properly trained reason from natural principles: let him be anathema.Faith is above reason but there can never be any true contradiction between faith and reason.
