Trinity details?

I would go for the three parts. The Spirit really isn't a person, anyway, and neither is God. The Son is the only one that became a person. Being a Catholic also, it is a difficult concept to grasp. You may find it comforting, however, that you can pray to God, who came to humankind in his Son, and and speaks to you through the Holy Spirit. Do you think of yourself and your soul as two different beings? Wouldn't that be comparable to God and His Spirit?
