non-Catholics will never understand that point, well said.
( how can they when they think there were no Christians before the 16th century? )
When I was growing up they were not referred to as 'Christians', they were 'Protestants' ... those who had separated from the Church of Rome and groups descended from them.
When did it all change ... like '4x4s' becoming 'SUVs' and a group of people hijacking the word 'gay' which once meant 'happy'...???
