Without speaking for religions I'm not familiar with, I grew up Catholic, and one of the most important Catholic beliefs is that during Mass, the bread (i.e. "communion" wafers) and wine quite literally transform into the body and blood of Jesus, and that eating and drinking it is a necessary ritual to get into heaven[1], which was a source of controversy even back as far as the Protestant Reformation, with some sects retaining that doctrine and others abandoning it. In a lot of ways, what's considered "normal" or "crazy" in a religion comes to what you're familiar with.
For those not familiar with the bible enough to know what to look for to find the wild stuff, look up the story of Elisha summoning bears out of the first to maul children for calling him bald, or the last two chapters of Daniel (which I think are only in the Catholic bible) where he literally blows up a dragon by feeding it a cake.
