I don't follow a Pope either.
Your statements here are fallaciously begging the question as to who Jesus is. The most important question a man can be asked is found in the gospels: "But who do you say that I am?" You say one must put their trust in Jesus for salvation, and you are correct, but which Jesus? The one you believe in is different from the one I believe, and the one I believe in is the one found in the Athanasian and Nicene Creeds, and hence, in the Bible.
The "isms" are simply ways of stating what one believes without having to state everything relevant to that belief. Similar to the Creeds, they are summations, albeit in one word.
These two posts, to me, appear to be implicit admissions that you now don't believe the Athanasian Creed to be correct. Is that about right?
