Massuet, indeed, argues at great length(44) against the idea that there was any other bishop in Gaul than the bishop of Lyons; but all his arguments resolve themselves into the one, that there is no mention made in any early writer of any other. On this ground one might, with equal reason, conclude that there were no bishops in Britain before the council of Arles, when they are first mentioned. But until it can be shown that there is an instance in any writer anterior to Eusebius, or of his time, of the use of the term παροικία to signify a parochial church or parish, the simple use of this word by him is sufficient evidence against all negative arguments whatever. What the author of the Acts of the Martyrdom of St. Saturninus says(45) of the fewness of churches in Gaul in his time is really no contradiction to this opinion; for if there were at that time as many as twenty or thirty, it would be extremely few, considering the extent of the country. I have said that we have no record of the operations of Irenæus as bishop of Lyons. I mean, that we know of nothing which he did in that particular church. He bore, in a general way, the character of “the light of the western(46) Gauls,” and is said to have “cultivated and enlightened the Celtic nations(47).” And in consonance with this there is a tradition(48), though of comparatively recent date, that he sent a priest and deacon as missionaries to Besançon, and a priest and two deacons to Valence, in Dauphiné. The circumstance is very probable in itself, and is in agreement with the traditions of those Churches.
