Little children, these are the end times, and as you heard that the Antichrist is coming, even now many antichrists have arisen. By this we know that it is the end times.
But how can that passage agree with the words of John, who says that there were already many antichrists? To this I reply, that John meant no other thing than to say, that some particular sects had already risen, which were forerunners of a future Antichrist; for Cerinthus, Basilides, Marcion, Valentinus, Ebion, Arrius, and others, were members of that kingdom which the Devil afterwards raised up in opposition to Christ. Properly speaking, Antichrist was not yet in existence; but the mystery of iniquity was working secretly. But John uses the name, that he might effectually stimulate the care and solicitude of the godly to repel frauds.
