The hope that truth and wisdom would be found in the assemblies of the orthodox clergy induced the emperor to convene, at Constantinople, a synod of one hundred and fifty bishops, who proceeded, without much difficulty or delay, to complete the theological system which had been established in the council of Nice. The vehement disputes of the fourth century had been chiefly employed on the nature of the Son of God; and the various opinions, which were embraced concerning the Second, were extended and transferred, by a natural analogy, to the Third, person of the Trinity.42 Yet it was found, or it was thought, necessary, by the victorious adversaries of Arianism, to explain the ambiguous language of some respectable doctors; to confirm the faith of the Catholics; and to condemn an unpopular and inconsistent sect of Macedonians, who freely admitted that the Son was consubstantial to the Father, while they were fearful of seeming to acknowledge the existence of Three Gods. A final and unanimous sentence was pronounced to ratify the equal Deity of the Holy Ghost; the mysterious doctrine has been received by all the nations and all the churches of the Christian world;
[42 ]Le Clerc has given a curious extract (Bibliothèque Universelle, tom. xviii. p. 91-105) of the theological sermons which Gregory Nazianzen pronounced at Constantinople against the Arians, Eunomians, Macedonians, &c. He tells the Macedonians, who deified the Father and the Son, without the Holy Ghost, that they might as well be styled Tritheists as Ditheists. Gregory himself was almost a Tritheist; and his monarchy of heaven resembles a well-regulated aristocracy.
