I always believed in God, I would go to mass most of the time, but I had no idea of the calling to holiness.
Catholic theology believes that God gave man free will, and you can't give somebody free will and then send in a play from the sidelines.
I think of myself as being a relatively intelligent man who is open to a lot of different things and I think that questioning our purpose in life and the meaning of existence is something that we all go through at some point.
