Marcion was, according to the better account, a wealthy shipowner of Pontus and probably a convert to Christianity[689]. He seems to have been born at Sinope, at one time the most important of the Greek towns on the Southern shore of the Euxine or Black Sea. Mithridates the Great, who was also born there, had made Sinope his capital, and though it had no doubt declined in rank since his time, it must still have been, in the year 100 A.D. (the probable date of Marcion’s birth), a flourishing and prosperous place[690]. As in all the cities of Asia Minor, the Stoic philosophy had there obtained a firm hold, and there is some reason for thinking that Marcion received lessons in this before his conversion[691]. Of the circumstances which led to this event we have no knowledge, and it was even said in later times that he was born a Christian, and that his father had been a bishop of the Church. A better founded story is that, on his conversion, he brought into the common fund of the Church a considerable sum of money, which is said to have been paid out to him on his expulsion[692]. When at the mature age of forty he went to Rome, it seems reasonable to suppose that he accepted the orthodox teaching, as it is said that there was some talk of his being made bishop of what was even then the richest and highest in rank of all the Christian Churches. At Rome, however, he fell in with one Cerdo, a Syrian, who seems to have been already domiciled there and to have taught in secret a pronouncedly dualistic system in which God and Matter were set in sharp opposition to one another, and in which it was held that a good God could not have been the author of this wicked world[693]. This opinion Marcion adopted and elaborated, with the result that he was expelled from the Catholic Church, and thereupon set to work to found another, having bishops, priests, deacons, and other officers in close imitation of the community he had left[694]. It is said that before his death he wished to be reconciled to the Church, but was told that he could only be readmitted when he had restored to the fold the flock that he had led away from it. This, on the authority of Tertullian, he would have been willing to do; but his rival Church had by that time so enormously increased in numbers, that he died, probably in 165 A.D., before he was able to make the restitution required[695]. This story also can only be accepted with a great deal of reserve[696].
