I think I posted this response actually on the wrong thread (you know the other one!) - but the "Virgin Mary" got my attention. I'm going to check around, but as far as I know, nothing (no words)in the Nicene Creed have changed since 340ish.
Talk to you later!
As far as I know, the only language change in the Nicene Creed since the 4th century is the one that is so critical to the debates between Orthodox and Roman Catholics - the addition of the so-called filoque (sp?) The Creed as I quoted it says the Holy Spirit "proceedeth from the Father." I believe the Roman Catholic version of the Nicene Creed says "from the Father and the Son," which leads to what the Orthodox consider "dual-procession" doctrine and a diminishment of the Holy Spirit.
Christ Bless!
