Yes, because if there was no God then I would have to reject the notion of objective truth altogether and as it turns out what I believe is in my estimation the best of all possible beliefs even in a world where nothing were strictly true in an objective sense--I will add that is by a long shot. My academic background is in Western philosophy (epistemology and the philosophy of science) additionally I spent two decades studying Mahayana Buddhism through various Tibetan schools, along with the general religious context in which Buddhism arose, as well as being a declared, if not always committed, Baha'i (until Catholicism I never had a firm faith in God. I declared with the knowledge of the world I then held in which I concluded that it was most probable that Baha'u'llah was telling the truth about his experience. Consequently I cycled through at various stages believing in materialism, a Buddhist worldview, and attempting to sincerely accept the theism of the Baha'i Faith).
I am a Catholic not just by conviction, but also, as it turns out, by default.
