It is. It means all the foundational, self-serving claims of the RCC are not found in the Creeds. Perhaps because they aren't found in Scripture.
How interesting your reply is; to me it means that the Church (Catholic Church that your posts so often denigrate, as the above does) never bothered to define authority precisely because no one had thought to make it matter of debate because all Christians within the Catholic Church of that time accepted the Church's authority as fundamental to being a Christian, which it was and still is.
You have a war to wage, Josiah, a constant combat against this or that, with the Catholic Church being one of this or that. It is wearisome to have nearly every post that I write turned into an occasion for more war. And this is the chief reason why my contributions in CH have declined. So I spend my time elsewhere.
PS: I am writing this at 22:30 Perth time, not especially late, and I am not tired or grumpy at the time of writing, but I came to your post after writing a number of posts in 'elsewhere' to people who manage to avoid the truculent denunciation of "the RCC" which slips into so many of your replies to me. So, cheers Josiah, we can engage another day, your post is the only reply to my posts here today, so, I am finished for the day.
