On p. 48, Dr. Tischendorf quotes Irenæus, whose writings belong to the extreme end of the second century, as though that Bishop must be taken as vouching the four Gospels as we now have them. Yet, if the testimony of Irenæus be reliable (“Against Heresies,” Book III, cap. i.) the Gospel attributed to Matthew was believed to have been composed in Hebrew, and Irenæus says that as the Jews desired a Messiah of the royal line of David, Matthew having the same desire to a yet greater degree, strove to give them full satisfaction. This may account for some of the genealogical curiosities to which we have drawn attention, but hardly renders Matthew’s Gospel more reliable; and how can the suggestion that Matthew wrote in Hebrew prove that Matthew penned the first Gospel, which has only existed in Greek? Irenæus, too, flatly contradicts the Gospels by declaring that the ministry of Jesus extended over ten years and that Jesus lived to be fifty years of age (“Against Heresies,” Book II, cap. 22). If the statement of Irenæus (“Against Heresies,” Book III, cap. xi) that the fourth Gospel was written to refute the errors of Cerinthus and Nicolaus, have any value, then the actual date of issue of the fourth Gospel will be considerably after the others. Dr. Tischendorf’s statement that Polycarp has borne testimony to the Gospel of John is not even supported by the quotation on which he relies. All that is said in the passage quoted (Eusebius, “Ecc. Hist,” Book V, cap. 20) is that Irenæus when he was a child heard Polycarp repeat from memory the discourses of John and others concerning Jesus. If the Gospels had existed in the time of Polycarp it would have been at least as easy to have read them from the MS as to repeat them from memory. Dr. Tischendorf might also have added that the letter to Florinus, whence he takes the passage on which he relies, exists only in the writings of Eusebius, to whom we are indebted for many pieces of Christian evidence since abandoned as forgeries. Dr. Tischendorf says: “Any testimony of Polycarp in favor of the Gospel refers us back to the Evangelist himself, for Polycarp, in speaking to Irenæus of this Gospel as the work of his master, St. John, must have learned from the lips of the apostle himself, whether he was its author or not.” Now, what evidence is there that Polycarp ever said a single word as to the authorship of the fourth Gospel, or of any Gospel, or that he even said that John had penned a single word? In the Epistle to the Philippians (the only writing attributed to Polycarp for which any genuine character is even pretended), the Gospel of John is never mentioned, nor is there even a single passage in the Epistle which can be identified with any passage in the Gospel of John.
