The chief accusations urged against the early Christians by their antagonists were atheism, cannibalism, and incest. These charges were made very early. Justin Martyr (Apol. I. 26) mentions them, and Pliny in his epistle to Trajan speaks of the innocent meals of the Christians, implying that they had been accused of immorality in connection with them. (Compare, also, Tertullian’s Apol. 7, 8, and Ad Nationes, 7.) In fact, suspicions arose among the heathen as soon as their love feasts became secret. The persecution in Lyons is to be explained only by the belief of the officers that these and similar accusations were true. The Christians commonly denied all such charges in toto, and supported their denial by urging the absurdity of such conduct; but sometimes, as in the present case, they endeavored to exonerate themselves by attributing the crimes with which they were charged to heretics. This course, however, helped them little with the heathen, as the latter did not distinguish between the various parties of Christians, but treated them all as one class. The statement of Eusebius in the present case is noteworthy. He thinks that the crimes were really committed by heretics, and occasioned the accusations of the heathen, and he thus admits that the charges were founded upon fact. In this case he acts toward the heretics in the same way that the heathen acted toward the Christians as a whole. This method of exonerating themselves appears as early as Justin Martyr (compare his Apol. I. 26). Irenæus also (I. 25, 3), whom Eusebius substantially follows in this passage, and Philaster (c. 57), pursue the same course.
