Adv. Hær. IV. 27. 1, where Irenæus mentions a “certain presbyter who had heard it from those who had seen the apostles,” &c. Who this presbyter was cannot be determined. Polycarp, Papias, and others have been suggested, but we have no grounds upon which to base a decision, though we may perhaps safely conclude that so prominent a man as Polycarp would hardly have been referred to in such an indefinite way; and Papias seems ruled out by the fact that the presbyter is here not made a hearer of the apostles themselves, while in V. 33. 4 Papias is expressly stated to have been a hearer of John,—undoubtedly in Irenæus’ mind the evangelist John (see above, Bk. III. chap. 39, note 4). Other anonymous authorities under the titles, “One superior to us,” “One before us,” &c., are quoted by Irenæus in Præf. §2, I. 13. 3, III. 17. 4, etc. See Routh, Rel. Sacræ, I. 45–68.
