Ecclesiastical historians Epist. ad Petrum Fullonem; Theoph., Ad Arn. 5930., then, say that once when the people of Constantinople were offering prayers to God to avert a threatened calamity See Niceph. Call., Hist. xviii. 51., during Proclus’ tenure of the office of Archbishop, it happened that a boy was snatched up from among the people, and was taught by angelic teachers the “Thrice Holy” Hymn, “Thou Holy God, Holy and Mighty One, Holy and Immortal One, have mercy upon us:” and when once more he was restored to earth, he told what he had learned, and all the people sang the Hymn, and so the threatened calamity was averted. And in the fourth holy and great Œcumenical Council, I mean the one at Chalcedon, we are told that it was in this form that the Hymn was sung; for the minutes of this holy assembly so record it Conc. Chal., Act. 1, at the end.. It is, therefore, a matter for laughter and ridicule that this “Thrice Holy” Hymn, taught us by the angels, and confirmed by the averting of calamity In Cod. S. Hil. is written above the line ἢ θεηλάτου ὀργῆς παύσει, which explains the author’s meaning., ratified and established by so great an assembly of the holy Fathers, and sung first by the Seraphim as a declaration of the three subsistences of the Godhead, should be mangled and forsooth emended to suit the view of the stupid Fuller as though he were higher than the Seraphim. But oh! the arrogance! not to say folly! But we say it thus, though demons should rend us in pieces, “Do Thou, Holy God, Holy and Mighty One, Holy and Immortal One, have mercy upon us.”
