Granted such a world let us take the second point and see what was the distance in mere time between this early third century of which I speak and what is called the Apostolic period; that is, the generation which could still remember the origins of the Church in Jerusalem and the preaching of the Gospel in Grecian, Italian, and perhaps African cities. We are often told that changes “gradually crept in;” that “the imperceptible effect of time” did this or that. Let us see how these vague phrases stand the test of confrontation with actual dates. Let us stand in the years 200-210, consider a man then advanced in years, well read and traveled, and present in those first years of the third century at the celebration of the Eucharist. There were many such men who, if they had been able to do so, would have reproved novelties and denounced perverted tradition. That none did so is a sufficient proof that the main lines of Catholic government and practice had developed unbroken and unwarped from at least his own childhood. But an old man who so witnessed the constitution of the Church and its practices as I have described them in the year 200, would correspond to that generation of old people whom we have with us today; the old people who were born in the late twenties and thirties of the nineteenth century; the old people who can just remember the English Reform Bill, and who were almost grown up during the troubles of 1848 and the establishment of the second Empire in Paris: the old people in the United States who can remember as children the election of Van Buren to the office of President: the old people whose birth was not far removed from the death of Thomas Jefferson, and who were grown men and women when gold was first discovered in California.
