Yeah to worship something God created would be idolatry.

The Trinity is confusing, how can God be three..... but also one? But here is another thought, what if God doesn't care if we can comprend Him? If He exists, being infinite and omniscient, and we are his creations, wouldn't his "being" be too much for us to comprehend? I find Christianity easier to believe in because it doesn't make sense. The Bible has a bunch of weird and baffling stories, if it was all made up, who the hell would include all the incest? Something fabricated would be a lot more convenient.
