What is the difference between Catholic and Christian weddings?
Roman Catholic Answer No difference, Catholic and Christian is the same thing. I imagine that you are asking the difference between a Catholic/Christian Bible and a protestant Bible, which protestants may refer to as a Christian Bible. Protestants have removed a number of books from the Old Testament as they were uncomfortable with not believing things that the Bible said, so they changed the Bible.
Catholics are Christian. Roman Catholic Answer There is no difference between a Catholic and a Christian according to the traditional interpretation of these two words, unfortunately, since the time of the protestant revolt, heretics have appropriated the word "Christian" to mean someone who believes in their own version of Jesus Christ and their own version of the Bible, and excludes Catholics.
