So manifestly has Justin gone to other sources than our four Gospels that Canon Sanday admits: "Either Justin has used a lost gospel or gospels, besides those that are still extant, or else he has used a recension of these gospels with some slight changes of language and some apocryphal additions" ("The Gospels in the Second Century," p. 129; 1876). We conjecture that the "Memoirs" of Justin were the materials from which our Gospels were compiled, and that they were similar to or used in conjunction with the Gospel according to the Hebrews. Credner argues that he used the Gospel of Peter. It is noticeable that the Diatessaron of Justin's pupil, Tatian, was called by Epiphanius the Gospel according to the Hebrews. Theodoret tells us that the Nazarenes made use of the Gospel of Peter, and we know by the testimony of the Fathers generally that the Nazarene Gospel was that commonly called the Gospel according to the Hebrews. That Justin used this once celebrated Gospel seems all the more probable since we have the express testimony of Eusebius ("Ec. History, iv.," 22) that it was used by Hegesipus, his contemporary and compatriot. ELEUTHERIUS Nearly all our information concerning this worthy is derived from Eusebius. He was born in Palestine of Jewish parents, and wrote five books of memoirs or commentaries no longer extant. As he therein mentions Pope Eleutherius they must have been written after B.C. 177. The date 185 is a probable one. The work of Hegesippus appears to have been the earliest attempt to give a history of early Christianity, and as it is evident he represented the Jewish anti-Pauline school, which eventually was swamped by the Gentile element, the loss or destruction of his writings is much to be regretted. Such fragments as Eusebius has thought proper to preserve certainly makes one curious for more. The longest fragment concerns no less a person than the brother of the incarnate God. Eusebius gives it in the second book of his "Ecclesiastical History," chap, xxiii., from which we extract the following:--
