Did Catholic create Christian

Answer 1

Not real sure what you are asking here, as Catholic and Christian mean the same thing, although many in the modern world use Christian to mean something other than Catholic. In its original meaning, Catholic and Christian are identical, so one did not create the other. If you are asking about protestants, when you use the word, Christian, then, no, certainly not, as Protestantism is a heresy which has been condemned by the Church in no uncertain terms. If you are using "Christian" in that sense, then the answer is "no", they created themselves as apart from Christ's church and in making their own church are trying to appropriate the word Christian to themselves.
