Sandro Magister on the text that Paul VI proclaimed from St. Peter's Square at the end of the "Year of Faith" in 1968. Apparently, the text was pretty much one proposed by the French philosopher Jacques Maritain.
I've never actually read the Credo of the People of God.
I have, however, read the Dutch Catechism. It was what was used during my catechumenate, as I was preparing for Baptism. :: sigh ::
[Aside: I guess I need to add The Peasant of Garonne to the to read list!]
