Technically “Roman Catholic” is wrong. The Church is the Catholic Church. There is a Roman (or Latin) Rite within the Catholic Church. The Anglicans started to call the Catholic Church the “Roman Catholic Church” because they continued to argue that they were Catholic also. The label has come into common use, but it is not the name of the Church.
You’re right, of course. Thanks for the reminder! (I won’t blame the Anglicans for my error, since they’re Guinness-drinking FRiends :-).
