Christian apologist, born at Flavia Neapolis, about A.D. 100, converted to Christianity about A.D. 130, taught and defended the Christian religion in Asia Minor and at Rome, where he suffered martyrdom about the year 165. Two “Apologies” bearing his name and his “Dialogue with the Jew Tryphon” have come down to us. Leo XIII had a Mass and an Office composed in his honour and set his feast for 14 April.
Among the Fathers of the second century his life is the best known, and from the most authentic documents. In both “Apologies” and in his “Dialogue” he gives many personal details, e.g. about his studies in philosophy and his conversion; they are not, however, an autobiography, but are partly idealized, and it is necessary to distinguish in them between poetry and truth; they furnish us however with several precious and reliable clues. For his martyrdom we have documents of undisputed authority. In the first line of his “Apology” he calls himself “Justin, the son of Priscos, son of Baccheios, of Flavia Neapolis, in Palestinian Syria”. Flavia Neapolis, his native town, founded by Vespasian (A.D. 72), was built on the site of a place called Mabortha, or Mamortha, quite near Sichem (Guérin, “Samarie”, I, Paris, 1874, 390-423; Schürer, “History of the Jewish People”, tr., I, Edinburgh, 1885). Its inhabitants were all, or for the most part, pagans. The names of the father and grandfather of Justin suggest a pagan origin, and he speaks of himself as uncircumcised (Dialogue, xxviii). The date of his birth is uncertain, but would seem to fall in the first years of the second century. He received a good education in philosophy, an account of which he gives us at the beginning of his “Dialogue with the Jew Tryphon”; he placed himself first under a Stoic, but after some time found that he had learned nothing about God and that in fact his master had nothing to teach him on the subject. A Peripatetic whom he then found welcomed him at first but afterwards demanded a fee from him; this proved that he was not a philosopher. A Pythagorean refused to teach him anything until he should have learned music, astronomy, and geometry. Finally a Platonist arrived on the scene and for some time delighted Justin. This account cannot be taken too literally; the facts seem to be arranged with a view to showing the weakness of the pagan philosophies and of contrasting them with the teachings of the Prophets and of Christ. The main facts, however, may be accepted; the works of Justin seem to show just such a philosophic development as is here described, Eclectic, but owing much to Stoicism and more to Platonism. He was still under the charm of the Platonistic philosophy when, as he walked one day along the seashore, he met a mysterious old man; the conclusion of their long discussion was that he soul could not arrive through human knowledge at the idea of God, but that it needed to be instructed by the Prophets who, inspired by the Holy Ghost, had known God and could make Him known (“Dialogue”, iii, vii; cf. Zahm, “Dichtung and Wahrheit in Justins Dialog mit dem Jeden Trypho” in “Zeitschr. für Kirchengesch.”, VIII, 1885-1886, 37-66).
The “Apologies” throw light on another phase of the conversion of Justin: “When I was a disciple of Plato”, he writes, “hearing the accusations made against the Christians and seeing them intrepid in the face of death and of all that men fear, I said to myself that it was impossible that they should be living in evil and in the love of pleasure” (II Apol., xviii, 1). Both accounts exhibit the two aspects of Christianity that most strongly influenced St. Justin; in the “Apologies” he is moved by its moral beauty (I Apol., xiv), in the “Dialogue” by its truth. His conversion must have taken place at the latest towards A.D. 130, since St. Justin places during the war of Bar-Cocheba (132-135) the interview with the Jew Tryphon, related in his “Dialogue”. This interview is evidently not described exactly as it took place, and yet the account cannot be wholly fictitious. Tryphon, according to Eusebius (Hist. eccl., IV, xviii, 6), was “the best known Jew of that time”, which description the historian may have borrowed from the introduction to the “Dialogue”, now lost. It is possible to identify in a general way this Tryphon with the Rabbi Tarphon often mentioned in the Talmud (Schürer, “Gesch. d. Jud. Volkes”, 3rd ed., II, 377 seq., 555 seq., cf., however, Herford, “Christianity in Talmud and Midrash”, London, 1903, 156). The place of the interview is not definitely told, but Ephesus is clearly enough indicated; the literary setting lacks neither probability nor life, the chance meetings under the porticoes, the groups of curious onlookers who stop a while and then disperse during the inteviews, offer a vivid picture of such extemporary conferences. St. Justin lived certainly some time at Ephesus; the Acts of his martyrdom tell us that he went to Rome twice and lived “near the baths of Timothy with a man named Martin”. He taught school there, and in the aforesaid Acts of his martyrdom we read of several of his disciples who were condemned with him.
In his second “Apology” (iii) Justin says: “I, too, expect to be persecuted and to be crucified by some of those whom I have named, or by Crescens, that friend of noise and of ostentation.” Indeed Tatian relates (Discourse, xix) that the Cynic philosopher Crescens did pursue him and Justin; he does not tell us the result and, moreover, it is not certain that the “Discourse” of Tatian was written after the death of Justin. Eusebius (Hist. eccl., IV, xvi, 7, 8) says that it was the intrigues of Crescens which brought about the death of Justin; this is credible, but not certain; Eusebius has apparently no other reason for affirming it than the two passages cited above from Justin and Tatian. St. Justin was condemned to death by the prefect, Rusticus, towards A.D. 165, with six companions, Chariton, Charito, Evelpostos, Pćon, Hierax, and Liberianos. We still have the authentic account of their martyrdom (“Acta SS.”, April, II, 104-19; Otto, “Corpus Apologetarum”, III, Jena, 1879, 266-78; P. G., VI, 1565-72). The examination ends as follows:
“The Prefect Rusticus says: Approach and sacrifice, all of you, to the gods. Justin says: No one in his right mind gives up piety for impiety. The Prefect Rusticus says: If you do not obey, you will be tortured without mercy. Justin replies: That is our desire, to be tortured for Our Lord, Jesus Christ, and so to be saved, for that will give us salvation and firm confidence at the more terrible universal tribunal of Our Lord and Saviour. And all the martyrs said: Do as you wish; for we are Christians, and we do not sacrifice to idols. The Prefect Rusticus read the sentence: Those who do not wish to sacrifice to the gods and to obey the emperor will be scourged and beheaded according to the laws. The holy martyrs glorifying God betook themselves to the customary place, where they were beheaded and consummated their martyrdom confessing their Saviour.”
