Tertullian is a writer who connects the age of apostolic men, as we may call the men who knew the Apostles--Ignatius, Polycarp, Clement of Rome, and such like--with the third century. Tertullian was born about the middle of the second century, and he lived till the third century was well advanced. He was one of those persons whose chronological position enables them to transmit historical facts and details from one critical point to another. Let me illustrate what I mean by a modern example. Every unprejudiced thinker will acknowledge that the Rev. John Wesley was a man who exercised an extraordinary religious influence. He not only originated a vast community of world-wide extent, which calls itself after his name, but he also imparted a tremendous impetus to spiritual life and work in the Church of England. After the departure of Mr. Wesley from this life his mantle fell upon a certain number of his leading followers, men like Adam Clarke, the commentator; Jabez Bunting, the organizer of modern Wesleyanism; Thomas Coke, Robert Newton, and Richard Watson, the author of the _Institutes of Theology_. Several of these men lived far into this century, and there are at the present day thousands still alive who recollect some of them, while there are many still alive who can recollect all of them. Now let us draw a parallel with all reverence, and yet with perfect fairness. John Wesley began his life at the beginning of the eighteenth century as our Lord began His human life at the beginning of the first century. John Wesley's immediate disciples perpetuated their lives till the middle of the present century. Our Lord's apostles and immediate followers perpetuated their lives in some cases till well into the second century. At the close of the nineteenth century there are hundreds, to say the least, who remember Adam Clarke and Thomas Coke, who in turn were personally acquainted with John Wesley. In the last quarter of the second century there must have been many still alive--apostolic men, I have called them--whose youthful memories could bear them back to the days when the Apostle St. John, and men like St. Mark, and St. Luke, and St. Ignatius, still testified what they had personally seen and heard and known. Why, the simple fact is this, that in the year 1950 there will be still living numerous persons who will be able to say that they have personally known many individuals who were the friends and acquaintances of John Wesley's immediate disciples. Four long lives of ninety years, the one overlapping the other, will easily cover three centuries of time.
