Another period of seventy years runs on, and we come to the just-cited testimony of Cyprian, who therefore said nothing new, nor anything exaggerated; but when the truth was assailed in its very citadel, he spoke out and described wherein its strength lay. He gathers up and gives expression to the two hundred and twenty years between the day of Pentecost and his own time. Here are the creative words of our Apostle and High-priest explained and attested and exhibited as having passed into fact by four witnesses, first S. Paul, then S. Ignatius, thirdly S. Irenæus, fourthly S. Cyprian. Between all the five there is no shadow of divergence, between the Master who designed the building and the servants who described its erection; between the Prophet who foretold and the historians who recorded. The one said, Upon this rock I will build my Church; the others pointed out that the work was accomplished. The original and fundamental conception of all this work is expressed by S. Matthew and S. Mark when they speak of our Lord at His first going forth as “proclaiming the gospel of the kingdom.” His three years’ ministry is the germ and type of the perpetual mission which He founded. It was to be from first to last a work of personal ministry, beginning from above, not spreading from below; its power and virtue descending from Him through those whom He chose, the people being the work of the Prince, their government a delegation from Him, as their moral condition lay in following Him, and their life and support in feeding on Him. And He declared that the original conception should be carried out to the end, and that “the gospel of the kingdom” should be proclaimed through the whole world as a witness to all nations, until the consummation should come.(295) The chief events of the third century brought out more and more the unity of the Church and the Primacy of S. Peter’s See as the power within the Church by which that unity is produced and maintained.
