spirit he was anxious to deal gently with the "lapsed" (Eus. H. E. vi. 42); he pressed upon Novatian the duty of self-restraint, for the sake of the peace of the church, a.d. 251 (ib. vii. 45; Hieron. l.c.); and with better results counselled moderation in dealing with the rebaptism of heretics, in a correspondence with popes Stephen and Sixtus (a.d. 256-257) (Eus. H. E. vii. 5, 7, 9). His last letter (or letters) regarding Paul of Samosata seem to have been written in a similar strain. He charged the assembled bishops to do their duty, but did not shrink from appealing to Paul also, as still fairly within the reach of honest argument (Theod. Haer. Fab. ii. 8). In one instance Dionysius met with immediate success. In a discussion with a party of Chiliasts he brought his opponents to abandon their error (Eus. H. E. vii. 24.). His own orthodoxy, however, did not always remain unimpeached. When controverting the false teaching of Sabellius, the charge of tritheism was brought against him by some Sabellian adversaries, and entertained at first by his namesake Dionysius of Rome. Discussion shewed that one ground of the misunderstanding was the ambiguity of the words used to describe "essence" and "person," which the two bishops took in different senses. Dionysius of Rome regarded ὑπόστασις as expressing the essence of the divine nature; Dionysius of Alexandria as expressing the essence of each divine person. The former therefore affirmed that to divide the ὑπόστασις was to make separate gods; the latter affirmed with equal justice that there could be no Trinity unless each ὑπόστασις was distinct. The Alexandrine bishop had, however, used other phrases, which were claimed by Arians at a later time as favouring their views. Basil, on hearsay, as it has been supposed (Lumper, Hist. Patrum, xiii. 86 f.), admitted that Dionysius sowed the seeds of the Anomoean heresy (Ep. i. 9), but Athanasius with fuller knowledge vindicated his perfect orthodoxy. Dionysius has been represented as recognizing the supremacy of Rome in the defence which he made. But the fragments of his answer to his namesake (Athan. de Sent. Dionysii, ἐπέστειλε Διονυσίῳ δηλῶσαι . . . for the use of ἐπιστέλλω see Eus. H. E. vi. 46, etc.) shew the most complete and resolute independence; and there is nothing in the narrative of Athanasius which implies that the Alexandrine bishop recognized, or that the Roman bishop claimed, any dogmatic authority as belonging to the imperial see. To say that a synod was held upon the subject at Rome is an incorrect interpretation of the facts.
Dionysius was a prolific writer. Jerome (l.c.) has preserved a long but not exhaustive catalogue of his books. Some important fragments remain of his treatises On Nature (Eus. Praep. Ev. xiv. 23 ff.), and On the Promises, in refutation of the Chiliastic views of Nepos (Eus. H. E. iii. 28, vii. 24, 25); of his Refutation and Defence, addressed to Dionysius of Rome, in reply to the accusation of false teaching on the Holy Trinity (Athan. de Sent. Dionysii; de Synodis, c. 44; de Decr. Syn. Nic. c. 25); of his Commentaries on Ecclesiastes and on St. Luke, and of his books Against Sabellius (Eus. Praep. Ev. vii. 19).
The fragments of his letters are, however, the most interesting extant memorials of his work and character and of his time; and Eusebius, with a true historical instinct, has made them the basis of the sixth and seventh books of his history. The following will shew the wide ground covered:
a.d. 251.—To Domitius and Didymus. Personal experiences during persecution (Eus. H. E. vii. 11).
a.d. 251-252.—To Novatian, to the Roman Confessors, to Cornelius of Rome, Fabius of Antioch, Conon of Hermopolis; and to Christians in Alexandria, Egypt, Laodicaea, Armenia, on discipline and repentance, with pictures from contemporary history (ib. vi. 41, and vii. 45).
a.d. 253-257.—To Stephen of Rome, the Roman presbyters Dionysius and Philemon, Sixtus II. of Rome on Rebaptism (ib. vii. 4, 5, 7, 9).
a.d. 258-263.—To Germanus: incidents in persecution. Against Sabellians. A series of festal letters, with pictures of contemporary history (ib. vii. 11, 22 ff., 26).
a.d. 264.—To Paul of Samosata (vi. 40).
To these, of some of which only the titles remain, must be added an important canonical letter to Basilides, of uncertain date, discussing various questions of discipline, and especially points connected with the Lenten fast (cf. Dittrich, pp. 46 ff.). All the fragments repay careful study. They are uniformly inspired by sympathy and large-heartedness. His criticism on the style of the Apocalypse is perhaps unique among early writings for clearness and scholarly precision (Eus.H. E. vii. 25).
The most accessible and complete collection of his remains is in Migne's Patr. Gk. x. pp. 1233 ff., 1575 ff., to which must be added Pitra, Spicil. Solesm. i. 15 ff. A full monograph on Dionysius by Dittrich (Freiburg, 1867) supplements the arts. in Tillemont, Maréchal, Lumper, Moehler. An Eng. trans. of his works is in the Ante-Nicene Lib., and his Letters, etc., have been ed. by Dr. Feltoe for the Camb. Patristic Texts (1904).

Dionysius (7), bp. of Rome; a Greek by birth, consecrated July 22, a.d. 259, on the death of Xystus, in the persecution of Valerian. His efforts against heresy are recorded. When Dionysius of Alexandria (q.v.) was accused of holding doctrines akin to those of Sabellius, the Roman Dionysius wrote to him, and extracted so satisfactory a defence that he declared him purged of suspicion (Athan. Ep. de Sent. Dionys. Opp. i. 252; see an Eng. trans. of the Fragm. against Sabellius in Ante-Nicene Lib.). In 264 the Alexandrian and Roman Dionysii acted together with the council of Antioch in condemning and degrading Paul of Samosata. Dionysius of Rome died Dec. 26, 269.
[G.H.M.]
Dionysius (19), surnamed Exiguus because of his humbleness of heart, was a Scythian by birth, and a monk in the Western church under the emperors Justin and Justinian. To him we owe the custom of dating events from the birth of our Saviour, though he is now acknowledged to have placed the era four years too late. His collection of canons laid the foundation of canon law. He knew Latin and Greek fairly; though it is obvious that neither
