The meagreness of our information concerning the historic career of Jesus stands in striking contrast with the mass of information which lies within our reach concerning the primitive character of Christologic speculation. First we have the four epistles of Paul, written from twenty to thirty years after the crucifixion, which, although they tell us next to nothing about what Jesus did, nevertheless give us very plain information as to the impression which he made. Then we have the Apocalypse, written by John, A. D. 68, which exhibits the Messianic theory entertained by the earliest disciples. Next we have the epistles to the Hebrews, Philippians, Colossians, and Ephesians, besides the four gospels, constituting altogether a connected chain of testimony to the progress of Christian doctrine from the destruction of Jerusalem to the time of the Quartodeciman controversy (A. D. 70-170). Finally, there is the vast collection of apocryphal, heretical, and patristic literature, from the writings of Justin Martyr, the pseudo-Clement, and the pseudo-Ignatius, down to the time of the Council of Nikaia, when the official theories of Christ's person assumed very nearly the shape which they have retained, within the orthodox churches of Christendom, down to the present day. As we pointed out in the foregoing essay, while all this voluminous literature throws but an uncertain light upon the life and teachings of the founder of Christianity, it nevertheless furnishes nearly all the data which we could desire for knowing what the early Christians thought of the master of their faith. Having given a brief account of the historic career of Jesus, so far as it can now be determined, we propose here to sketch the rise and progress of Christologic doctrine, in its most striking features, during the first three centuries. Beginning with the apostolic view of the human Messiah sent to deliver Judaism from its spiritual torpor, and prepare it for the millennial kingdom, we shall briefly trace the progressive metamorphosis of this conception until it completely loses its identity in the Athanasian theory, according to which Jesus was God himself, the Creator of the universe, incarnate in human flesh.
