text: Yes, here is the reasoning:  The center of authority for the Catholic [apostolic] Church is Rome.  Administration is centered at the Vatican, Vatican City.  There are some 200 Christian denominations;  Lutheran, Methodist, Greek Orthodox and the list goes on. There are also many Christian religious orders.  Fundamentalist Christian Churches in a local community are a good example.  Some of the local Fundamentalist Churches are not recognized by the Catholic authority in Rome, therefore they are considered Christian but not Catholic.\n  To be Christian you are a believer of the teachings of Jesus Christ...to be Catholic you are both a believer of the Teachings of Jesus Christ but also a practicing member of the Roman Catholic Church.  The word 'Catholic" means ''universal''.
