Actually, I meant the "Apostles Creed". Sorry.
The Apostles Creed exists in two forms; the original "Roman Creed" and the more popular "Trent" version that was a part of the "Catechism of the Council of Trent" published in Feburary, 1562. The Roman Creed arose circa 200 AD and traces its roots directly to the Apostles. It was in the later that the phrase "the Communion of Saints" was added.
