Some people say that christians and catholics are very similar, but they do divide because of some major doctrinal issues. Such as mass or eucharist. Catholics believe that when we take communion that the wafer actually becomes the body of jesus and the wine or juice or whatever is used becomes the blood of jesus. Where as christians believe, that this is just symbolic and that christ body being broken and blood being shed was only to needed once to cover the sins of mankind. There are other differences, but I'm just doing this to clear the record. Agree, disagree why
