(374 A. D.). Amphilochius of Iconium, as Metropolitan of Lycaonia, wrote in concurrence with his bishops a synodal letter to the bishops of Lycia (another part of Asia Minor), which contains a statement of the orthodox doctrine (377 A. D.). In Constantinople (379) Gregory of Nazianzus pronounced his theological oration on this subject. The West likewise upheld the Catholic teaching in a synod held in Illyria and mentioned by Theodoret (H. E., IV, 8) and by Pope Damasus in his letter to Paulinus of Antioch. The sect was condemned in the First Council of Constantinople, and internal divisions soon led to its demise. Socrates (H. E., V, 24) states that a certain Macedonian presbyter, Eutropius, held conventicles of his own while others followed Bishop Carterius. Eustathius of Sebaste, Sabinus and Eleusius of Cyzicus seem to have been leaders whom the sect repudiated (for Eustathis, see Basil, Ep., CCLXIII, 3). In June 383, Emperor Theodosius I tried by means of a conference to bring the Arian factions to submission. Eleusius handed in his symbol of faith as representing the Macedonians, as he had represented them with Marcianus of Lampsacus at the Ecumenical Council of Constantinople. After this fruitless attempt at reconciliation the Macedonians with other heretics incurred all the severities of the Theodosian code and within a generation disappeared from history. Socrates and Sozomus mention a certain Marathonius, made Bishop of Nicomedia by Macedonius, who obtained such a leading position in the sect that they were often styled after him Marathonians. Through St. Jerome, St. Augustine, St. Damasus and Rufinus, the name Macedonians became the customary designation in the West. No writings of Macedonius are extant, but Pneumatomachian writings are mentioned by Didymus the Blind, who wrote an excellent treatise on the Holy Ghost in thirty-six chapters (translated into Latin by St. Jerome at the command of Pope Damasus), and who refers in his later work (379) on the Trinity (II, 7, 8, 10) to some "Brief Expositions" of Macedonian doctrines which he possessed. Beliefs The Pneumatomachi (from Greek for “spirit" and "fighters”, combining as "Combators against the Spirit") are also known as the Macedonians. Church sources ascribe Bishop Macedonius I as the founder. The writings of Macedonius himself, as well as the Pneumatomachi, have all been lost, and what is asserted regarding their doctrine comes from polemic refutations by church leaders, who regarded them as a heretical sect.
