Yes, Catholic is a real religion. According to catholic tradition, Jesus Christ is the founder of catholic church. So I think "made" is not the right term. For me, Spanish only introduce it but they are not the one who made it. According to a blog I've read. "Calling catholics idolaters because they have image of christ and saints is based on misunderstanding. God forbade the worship of statues, but he did not forbid the religious use of statues."
