Am I to understand, in light of this post, you are Roman Catholic? I like to know to whom, or what, I am conversing with.
Yes, but the Athanasian Creed dates from the 7th Century, so if I were Greek Orthodox I would be making the same post. Must say the Greek speaks in less legalistic terms, so you might want to consult the Cappadocian Fathers to see how they talk about the Trinity.
