Tertullian by birth was a heathen and Carthaginian. He was the son of a centurion, and had been educated in all the varied learning of Greece and Rome. Skilled as a rhetorician and advocate in Rome, he brought, on his conversion to Christianity, the accomplishments of a highly cultivated intellect, but a sombre and irritable temper. The natural lawlessness of a mind guided by a passionate and stubborn disposition led him gradually to renounce the truths which the light of a higher intelligence had revealed, until at last he was anathematized for his Montanistic teachings. His writings are an invaluable addition to the Punic‐Latin theology, and a repository from which we receive great information concerning the polemic questions which at that period harassed the Christian church. Upon the subject of our article he writes as follows: “Let them, then, give us the origin of their churches; let them unfold the series of their bishops, coming down in succession from the beginning, so that the first bishop was appointed and preceded by any of the apostles, or apostolic men, who, nevertheless, preserved in communion with the apostles, had an ordainer and predecessor. For in this way the apostolic churches exhibit their origin; thus the Church of Smyrna relates that Polycarp was placed there by John, as the Church of Rome also relates that Clement was ordained by Peter.”(13) Again: “If thou be adjacent to Italy, there thou hast Rome, whose authority is near at hand to us. How happy is this church, to which the apostles poured forth their whole doctrine with their blood! where Peter is assimilated to our Lord; where Paul is crowned with a death like that of John.”(14) And again: “Let us see with what milk the Corinthians were fed by Paul; according to what rule the Galatians were reformed; what laws were to the Philippians, Thessalonians, Ephesians; what also the Romans sound in our ears, to whom Peter and Paul left the Gospel sealed with their blood.”(15) To this list of witnesses we might add the testimony of the fathers and ecclesiastical writers who have flourished in different ages of the church, but we now propose to briefly survey the opinions of some of the most noted Protestant commentators.
