They probably had good intentions, when they invented the Trinity concept or syncretized with pagans. I actually think syncretism is great. Its the dogma that's the danger. Great intentions and deep understanding can be lost in a single generation if people don't understand what's being said, and specifically that God is beyond all concepts. The error of the Trinity is that it limits God by way of definition, but it might not have in its original conception. Hang on, gotta find a verse that just popped in my head...
