The Body of Christ IS Christ. This is one of the very rich implications of the Incarnation. Is not Christ the Son of God come in the flesh? Which is to say, in His human nature, in His Body? As St.John says, “Many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh; such is the deceitful one and the antichrist.” 2 John 1:7
Yes, but it is the catholic who supplants the exclusive claim of salvation in only Christ as I noted in the Greek with the false promises of the apparitions claiming that the one that recommends themselves to it shall not perish.
