Creed of Gregory of Neocaesarea

Gregory Thaumaturgus, also known as Gregory of Nocaesarea or Gregory the Wonderworker, (ca. 213 – ca. 270) was a Christian bishop of the 3rd century. The theotokos and the Apostle John, (it is claimed), appeared to Gregory in a dream, and taught him about the holy trinity. Gregory wrote down what was revealed to him. this teaching was used by other fathers of the church: Basil the great, Gregory the Theologian, and Gregory of Nyssa. The Symbol of Gregory of Neocaesarea was later examined and affirmed in the year 325 by the first ecumenical council.

There is one God, the Father of the living Word, who is His subsistent Wisdom and Power and Eternal Image: perfect Begetter of the perfect Begotten, Father of the only-begotten Son.

There is one Lord, Only of the Only, God of God, Image and Likeness of Deity, Efficient Word, Wisdom comprehensive of the constitution of all things, and Power formative 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 Spirit, having His subsistence from God, and being made manifest by the Son, [to wit to men*]: Image of the Son, Perfect Image of the Perfect; Life, the Cause of the living; Holy Fount; Sanctity, the Supplier, or Leader, of Sanctification; in whom is manifested God the Father, who is above all and in all, and God the Son, who is through all.

There is a perfect Trinity, in glory and eternity and sovereignty, neither divided nor estranged. Wherefore there is nothing either created or in servitude in the Trinity; nor anything superinduced, as if at some former period it was non-existent, and at some later period it was introduced. And thus neither was the Son ever wanting to the Father, nor the Spirit to the Son; but without variation and without change, the same Trinity abides ever.
