Dionysius (3), bp. of Corinth, probably the successor of , placed by Eusebius in his Chronicle under 171, (see also Eus. H. E. ii. 25, iii. 4, iv. 21, 23, 35; Hieron. Catal. 27). He was the writer of certain pastoral letters, which gained so much authority in his own lifetime that heretics (probably the followers of Marcion) found it worth while, as he complains, to circulate copies falsified by interpolations and omissions. Eusebius mentions having met with 8 of these letters—viz. seven which he calls "Catholic Epistles," addressed to Lacedemon, Athens, Nicomedia, Gortyna and other churches in Crete, Amastris and other churches in Pontus, Cnossus and Rome; and one to "his most faithful sister Chrysophora." Probably the letters were already collected into a volume and enumerated by Eusebius in the order they occurred there, or he would probably have mentioned the two Cretan letters consecutively. Nothing remains of them, except the short account of their contents given by Eusebius, and a few fragments of the letter to the Roman church which, though very scanty, throw considerable light on the state of the church at the time. Eusebius praises Dionysius for having given a share in his "inspired industry" to those in foreign lands. A bp. of Corinth might consider Lacedaemon and Athens as under his metropolitan superintendence, but that he should send letters of admonition to Crete, Bithynia, and Paphlagonia not only proves the reputation of the writer, but indicates the unity of the Christian community. A still more interesting proof of this is furnished by the letter to the Roman church, which would seem to be one of thanks for a gift of money, and in which he speaks of it as a custom of that church from the earliest times to send supplies to churches in every city to relieve poverty, and to support the brethren condemned to work in the mines, "a custom not only preserved, but increased by the blessed bp. Soter, who administered their bounty to the saints, and with blessed words exhorted the brethren that came up as an affectionate father his children." The epithet here applied to Soter is usually used of those deceased in Christ; but there are instances of its application to living persons, and Eusebius speaks of him as still bishop when the letter of Dionysius was written. This letter is remarkable also as containing the earliest testimony that St. Peter suffered martyrdom in Italy at the same time as St. Paul. The letters indicate the general prevalence of episcopal government when they were written. In most of them the bishop of the church addressed is mentioned with honour; Palmas in Pontus, Philip and Pinytus in Crete, Soter at Rome. That to the Athenians reminds them of a former bp. Publius, who had suffered martyrdom during persecutions which reduced that church very low, from which condition it was revived by the zeal of Quadratus, the successor of Publius. This form of government was then supposed to date from apostolic times, for in the same letter Dionysius the Areopagite is counted as the first bp. of Athens; but the importance of the bishop seems to be still subordinate to that of his church. The letters, including that to Rome, are each addressed to the church, not to the bishop; and Soter's own letter, like Clement's former one, was written not in his own name, but that of his church (ὑμῶν τὴν ἐπιστολὴν). The letters, indeed, of Dionysius himself were written in his own name, and he uses the 1st pers. sing. in speaking of them, but adds that they were written at the request of brethren. Eusebius mentions two, Bacchylides and Elpistus, at whose instance that to the churches of Pontus was written.
