The ἔκθεσις τῆς πίστεως of Gregory Thaumaturgus.  cf. Ep. cciv. and the De Sp. Scto. § 74.  On the genuineness of the ἔκθεσις, vide D. C. Biog. i. 733.  cf. Dorner’s Christologie i. 737.  It is given at length in the Life of Greg. Thaumat. by Gregory of Nyssa, and is found in the Latin Psalter, written in gold, which Charlemagne gave to Adrian I.  Bp. Bull’s translation is as follows: “There is one God, Father of Him who is the living Word, subsisting Wisdom and Power and Eternal Impress, Perfect begotten of the Perfect, Father of the only begotten Son.  There is one Lord, Alone of the Alone, God of God, Impress and Image of the Godhead, the operative Word; Wisdom comprehensive of the system of the universe, and Power productive of the whole creation; true Son of true Father, Invisible of Invisible and Incorruptible of Incorruptible, and Immortal of Immortal, and Eternal of Eternal.  And there is one Holy Ghost, who hath His being of God, who hath appeared through the Son, Image of the Son, Perfect of the Perfect; Life, the cause of all them that live; Holy Fountain, Holiness, the Bestower of Sanctification, in whom is manifested God the Father, who is over all and in all, and God the Son, who is through all.  A Perfect Trinity, not divided nor alien in glory and eternity and dominion.”
