The letter against John of Jerusalem was written about the year 398 or 399, and was a product of the Origenistic controversy. Its immediate occasion was the visit of Epiphanius, bishop of Salamis in Cyprus, at Jerusalem, in 394. The bishop preached, in the Church of the Resurrection (§11), a pointed sermon against Origenism, which was thought to be so directly aimed at John that the latter sent his archdeacon to remonstrate with the preacher (§14). After many unseemly scenes, Epiphanius advised Jerome and his friends to separate from their bishop (§39). But how were they to have the ministrations of the Church? This difficulty was surmounted by Epiphanius, who took Jerome’s brother to the monastery which he had founded at Ad, in the diocese of Eleutheropolis, and there ordained him against his will, even using force to overcome his opposition (Jerome, Letter LI. 1). Epiphanius attempted to defend his action (Jerome, Letter LI. 2), but John, after some time, appealed to Alexandria against Jerome and his supporters as schismatics. The bishop, Theophilus, at once took the side of John: but a letter, written by his emissary Isidore and intended for John, fell into the hands of Jerome (§37). The letter showed that Isidore was coming as a mere partisan of John, and Jerome, therefore, treated both it and the bearer with secret contempt. The dispute was thus prolonged for about four years, and, after some attempts at reconciliation, and the exhibition of much bitterness, amounting to the practical excommunication of Jerome and his friends, the dispute was stopped, perhaps by Theophilus, perhaps through the influence of Melania. The letter written to Pammachius at Rome, in 397 or 398, against John, was abruptly broken off, and it is almost certain that it was never published during Jerome’s lifetime. Jerome afterwards had so much influence with Theophilus that we find him interceding for John, who had fallen under the Pontiff’s displeasure (Letter LXXXVI. 1).
The date of this treatise is the subject of controversy. In §1 Jerome says that he wrote after three years, that is, three years from the visit of Epiphanius to Jerusalem, which was in 394. This would give the date 397. At §14, also, he says that Epiphanius had been brooding over his wrongs for three years. Another note of time is found in the words of §43, that John had lately sought to obtain a sentence of exile against Jerome from that wild beast who threatened the necks of the whole world, that is, the Prefect Rufinus, who died at the end of 395. All these statements point to the year 397. On the other hand, at §17, he speaks of his Commentaries on Ecclesiastes and Ephesians as having been written about (ferme) ten years ago; and the preface to Ecclesiastes says that he had read Ecclesiastes with Blesilla at Rome about (ferme) five years ago, consequently, fifteen years before the writing of this treatise. Blesilla’s death was in 384. The reading of Ecclesiastes may, therefore, have been in 383. And the fifteen years would bring us to 398. Also, at §41, Jerome says, addressing John. You seem to have slept for thirteen years, implying that it was for thirteen years that the state of things complained of by John had existed, that is, the presence of the monks in his diocese, or, at least, their leaving their own dioceses. Jerome left Antioch, the diocese of his ordination, at the end of 385 or beginning of 386; these thirteen years, therefore, bring us to 399, the date adopted by Vallarsi. There is, however, an intimation in Pallad. Hist. Laus., c. 117, that Melania, the friend of Rufinus, gave assistance in the matter of the schism of nearly 400 monks who followed Paulinus, which is admitted to relate to the schism at Bethlehem, caused by the question of the ordination of Paulinianus. We know that Melania and Rufinus left Jerusalem early in 397, and that, before their departure, Jerome and Rufinus were reconciled. It would, therefore, seem most probable that the treatise, which is written with so much animosity against John, Rufinus’s fellow-worker, and contains invidious allusions to Rufinus himself (§11, your friends, who grin like dogs and turn up their noses, Jerome’s constant description of Rufinus), was written before the reconciliation of Rufinus and Jerome, that is, in the end of 386 or the beginning of 387, and that it was broken off and kept unpublished because the situation had changed. Vallarsi places it in 399. He quotes the passages which make for the later date, but strangely omits the more definite statements which make for the earlier. It should be added that the letter of Jerome (LXXXII.) to Theophilus is evidently written at the same time, and under the same feelings, as this treatise. and, if the arguments above given are valid, that letter must be placed in 397, not in 399, as stated in the note prefixed to it. The short letter (LXXXVI.) to Theophilus is, in that case, probably to be placed in 398 or 399, rather than 401, as there stated.
