"[Then] let this be known to all of you and to all the people of Israel: [It is] by the name of Jesus Christ of Nazareth, whom you crucified [but] whom God raised from [the] dead, [that] this [man] stands before you healed. [He] is ‘the stone you builders rejected, which has become [the] cornerstone.’ Salvation exists in no one else, for there is no other name under heaven given to men by which we must be saved.” Acts 4:10-12 PSB
St. Ignatius of Antioch (110 AD). Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church.
St. Augustine of Hippo (390 AD). We must hold to the Christian religion and to communication in her Church, which is catholic and which is called Catholic not only by her own members but even by all her enemies. For when heretics or the adherents of schisms talk about her, not among themselves but with strangers, willy-nilly they call her nothing else but Catholic. For they will not be understood unless they distinguish her by this name that the whole world employs in her regard.
St. Vincent of Lerins (434 AD). “Moreover, in the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all. For that’s truly and in the strictest sense Catholic, which, as the name itself and the reason of the thing declare, comprehends all universally.”
