By the Monarchy is meant the doctrine that the Second and Third Persons in the Ever-blessed Trinity are ever to be referred in our thoughts to the First as the Fountain of Godhead, vid. §15. note 9, and §19, note 6. It is one of the especial senses in which God is said to be one. Cf. Orat. iii. §15. vid. also iv. §1. ‘The Father is union, ἕνωσις,’ says S. Greg. Naz. ‘from whom and unto whom are the others.’ Orat. 42. 15. also Orat. 20. 7. and Epiph. Hær. 57. 5. Tertullian, before Dionysius, uses the word Monarchia, which Praxeas had perverted into a kind of Unitarianism or Sabellianism, in Prax. 3. Irenæus too wrote on the Monarchy, i.e. against the doctrine that God is the author of evil. Eus. Hist. v. 20. [see S. Iren. fragment 33, Ante-Nic. Lib.] And before him was Justin’s work de Monarchia, where the word is used in opposition to Polytheism. The Marcionites, whom Dionysius presently mentions, are also specified in the above extract by Athan. vid. also Cyril. Hier. Cat. xvi. 3. Epiphanius says that their three origins were God, the Creator, and the evil spirit. Hær. 42, 3. or as Augustine says, the good, the just, and the wicked, which may be taken to mean nearly the same thing. Hær. 22. The Apostolical Canons denounce those who baptize into Three Unoriginate; vid. also Athan. Tom. ad Antioch. 5. Naz. Orat. 20. 6. Basil denies τρεῖς ἀρχικαὶ ὑποστάσεις, de Sp. S. 38. which is a Platonic phrase.
