Do you mean the Nicene Creed that predates the formation of the RCC as it split from the Eastern /Greek Orthodox?
Yes I mean the Nicene creed that does not pre-date the Catholic church unless it was written before Peter was the Holy See of Rome.
There are 22 Catholic churches, not just the Eastern and Roman churches. When you look at what PBXVI said he was not talking about any of the 22.
