You got it backwards guest...Catholics are Christians but Christians are not Catholic, Roman, Greek Orthodox or whatever necessarily, althought he Catholic ones are Catholic, of which there are several groups. I don't know what percentage of Christians are Catholic..and we tend to not call ourselves Christians unless pressed because it is used more for Protestants and we were taught back then to separate ourselves from the Protestants...and Protestants would hate being called Catholic or catholic or Katholic or whatever. mg
