Do the catholic and christian (prodistant) teachings both describe GOD as divine

well im catholic and the teachings of my church make God sound Unrealistic in ways. kind of from a story book. I believe In God and Jesus and Im not saying he isn't like that i just want to knoe if the christian church teaches the same thing. Also do they teach differently about Jesus. Because he once was human and I have been tought he was still perfect. Does the christian church teach that as well?
