At first sight, Hermas might seem to have little in common with Irenæus; and, on many accounts, it would be preferable to pair him with Barnabas. But I feel sure that chronology forbids, and that the age of Irenæus, and of the martyrs of Lyons and Vienne, is the period which called for this work, and which accounts for its popularity and its diffusion among the churches. Its pacific spirit in dealing with a rising heresy, which at first was a puzzle to the Latins, which Pius was disposed to meet by this gentle antidote, with which Eleutherus, in the spirit of a pacificator, tampered to his own hurt, and by which Victor was temporarily compromised, met precisely what the case seemed to demand in the judgment of Western Christians. They could not foresee the results of Montanism: it was not yet a defined heresy. And even the wise prudence of Irenæus shows anxiety not too hastily to denounce it; “seeing,” as Eusebius affirms, “there were many other wonderful powers of divine grace yet exhibited, even at that time, in different churches.”
