Epiphanius Acoratus 118

(1) Let Peter again refute these people, censuring those around Ananias and saying, “You tested the Holy Spirit,” and he says, “You have not lied to man, but to God.”

(2) The Apostle [Paul] knows, as we often said, that the Holy Spirit is not alien from God, saying, “He searches the depths of God.” that which is not from the ousia of God is unable to search the depths of God.

(3) We know that the Father is Father, Son is Son, Holy Spirit is Holy Spirit, Trinity in unity. For one is the unity of the Father and Son and Holy Spirit, one ousia, one Lordship, one will, one church, one baptism, one faith.

(4) And let them cease they was are against the holy virgin of Christ and [his] chaste bride, that is, our mother, the holy church.

(5) For her children undertook, from the holy fathers, that is, the holy apostle, to protect the faith, and the same time both to pass it down to their children and to proclaim it.

(6) And from those whose sons you yourselves are, most honoured brothers, may also pass this teaching to your children.

(7) Thus saying these things and things similar to them from the divine Scriptures to establish yourselves and those listening to you, may you,, faithful and orthodox men, not cease teaching, guiding, instructing this holy faith of the catholic church, as the holy and only virgin of God undertook from the holy apostles of the Lord to protect [it].

(8) And thus help each other who are being catechised, who intend to come to holy baptism, not only to proclaim to their sons in the Lord “the believing,” but also to teach specifically, as the same mother of all, both you and us, “saying”:

(9) We believe in one God, almighty Father, Maker of heaven and earth, all things visible and invisible.

(10) And [we believe] in one Lord Jesus Christ, the only-begotten Son of God, who was begotten from the Father before all ages, that is from the ousia of the Father, Light from Light, true God from true God, begotten not made, homoouios with the Father, through whom all things came to be, both that which in the heavens and that which is on the earth, who for our sake of us men and for our sake of our salvation descended from the heavens, and was made flesh from the Holy Spirit and Mary the virgin and became man, and was crucified on our behalf in the time of Pontius Pilate and suffered and was buried, and rose on the third day according to the Scriptures and ascended into the heavens and is seated at the right hand of the Father, and is coming again with glory to judge the living and the dead, of who kingdom there will not be an end.

(11) And [we believe] in the Holy Spirit, the Lord and Giver of life, one who proceeds from the Father, the one who is worshipped and glorified together with the Father and the Son, the one who spoke through the prophets.

(12) [We believe] in one holy catholic and apostolic church. We confess one baptism for the forgiveness of sins; we await the resurrection of the dead and life of the future age. Amen.

(13) Those who say that there was ever [a time] when he was not and that before he was begotten he was not, or that he came to be out of non-existence or from another hypostasis or ousia saying that the Son of God is in flux or variable, these people the catholic and apostolic church anathematises.

(14) And this is the faith handed down from the holy apostles and <affirmed/written down> in a church [at] the holy city of all the holy bishops together then, more than three hundred ten in number.
