EUTYCHIANS was also the name of another sect, half Arian half Eunomian; which arose at Constantinople in the fourth century.
It being then a matter of mighty controversy among the Eunomians at Constantinople, whether or no the Son of God knew the last day and hour of the world, particularly with regard to that passage in the gospel of St. Matthew, chap. xxiv. ver. 36. or rather that in St. Mark, xiii. 32. where it is expressed, that the Son did not know it, but the Father only; Eutychius made no scruple to maintain, even in writing, that the Son did not know it; which sentiment displeasing the leaders of the Eunomian party, he separated from them, and made a journey to Eunomius, who was then in exile.—That heretic acquiesced fully in Eutychius's
doctrine, and admitted him to his communion. Eunomius dying soon after, the chief of the Eunomians at Constantinople refused to admit Eutychius; who, upon this, formed a particular sect of such as adhered to him, called Eutychians.
This same Eutychius, with one Theopronius, as was said in Sozomen's time, were the occasions of all the changes made by the Eunomians in the administration of baptism; which consisted, according to Nicephorus, in only using one immersion, and not doing it in the name of the Trinity, but in memory of the death of Jesus Christ. Nicephorus calls the chief of that sect, not Eutychius, but Eupsechius, and his followers Eunomian Eupsechians.
