Just imagine someone trying to explain to you as an adult how Catholics believe a wafer can double as the actual, literal body of Christ. There’s no way you would ever take that seriously. That’s why they have to get that stuff in your head before you’re old enough to think critically or ask questions. So many religious beliefs have power precisely because people accept them before they know how to challenge them.
Of course. This is exactly why preachers are so endlessly frantic to get children into Sunday School before they grow up.
