Math is about expresions, efficient when possible but math people understand that not everything can be expressed simply. They gun for as simply as they can, but some stuff is just not simple. Check out chaos theory, just looking at some of those equations will give you a migraine.
I'm not denying anything. The Creeds are very nice, they're a handy notecard version of The Church, but they don't even come close to expressing the whole. Human languages just can't express things that complex quickly. There's a reason you're expected to read the Bible and not just your 3x5 card with the Creeds, because the Creeds are just a start, the tip of the Faith iceburg.
I already told you what the base concept is: a species in whole or in part turning into 1 or more other species. The process by which we have fossil records of species no living person will ever see roaming the earth, and only very recent fossil records of the species we do see roaming the earth. Evolution is how the world of species changed from the place we see recorded in the fossil record to the one we inhabbit now. How A turned to B. We know there was A and we know there is B and we know something happened in between, the investigation of that something is the science of evolutionary theory.
Does sound difficult to arrange.

You're still not getting this. The four principal Creeds of The Church are dogmatic statements of the Faith, itself. Much more has been written, and lived, based on that confession of Faith.

And proudly and ignorantly interpret it wrongly, such that you might even believe the Creeds to be in error? You need a reliable translation, based on the original uncorrupted documents, fairly and faithfully translated at that. The Rheims, a primary source for your KJV, is the perfect example.
How A turned to B
Whatever you mean by that, you yourself claim to confess evolution. There is at least a theory, because you guys always talk about - the theory of evolution, not "a" theory, by the way (the theory). How's it stated? State it for me.
