QUOTE : Joseph Ratzinger commented that the opening line of the Nicene Creed, Credo in unum Deum (I believe in one God), is a subversive statement because it automatically rules out any rival claimant to ultimate concern. To say that one accepts only the God of Israel and Jesus Christ is to say that one rejects as ultimate any human being, any culture, any political party, any artistic form, or any set of ideas.
