I thought this set of passages from the book The Mountain of Silence, about E. Orthodox spirituality, was a pretty interesting take on the limits of philosophy and apologetics to "prove" the existence of God to yourself and others. When you think about all the non-believers who want some tangible proof of God these passages basically point to the idea that most of their criteria for proof will never work.
"You mentioned in your talk that Christians are misguided to assume that Christ taught that we should be unquestioning believers; that it was a mistake to believe that we should exert no effort in searching for evidence of the reality of God. What did you mean exactly?"
"Oh yes, now I recall. That would be a gross misunderstanding. In fact, Christ urged us to investigate the scriptures, to investigate, that is, God," Father Maximos responded as he remembered to buckle up.
"God loves, you see, to be investigated by us humans."
"So," I continued while keeping my eyes firmly on the road, "when Christians recite the Creed, that does not imply that we should accept God's existence blindly without testing whether in fact God is a reality or an illusion."
"That is absolutely true. It would be foolish to do so."
"For an academic like myself your words are very comforting. But the immediate question that comes to my mind," I continued, "is that if God indeed urges us to be inquisitive, how are we then supposed to conduct our research? Are we to turn to science, to philosophy, or to theology as our starting point?"
