Expositio fidei Nicaenae

Following the previously set faith, we anathematize the faith of Sabellius, which says that the same is Father and Son and Holy Spirit; for they err, as that the Father himself is the Son, and that the Son himself is the Father, and likewise the Holy Spirit, so that there is one person but three names. These things are alien to the faith; for we know Father as Father, Son as Son, Holy Spirit as the Spirit itself holy, one kingdom, one substance, one divinity. Further, we anathematize the faith of Photinus, which says that the Son is from Mary and from that point, and that he was not before this, but is spoken of prophetically in the scriptures, and that from Mary he is only according to divinity. We know these things are alien to the faith. For the Son always existed with the Father, having been born, and was with the Father, as it is written; for there was never a time when the Son was not, but the Father always had a Son; for it is impossible that a Father, once existing without a Son, should later be spoken of as Father by change, but always Father, always Son, as we have said before. He is not a brother, but having been born, he was with the Father, as has been written beforehand. And these things concerning the Father and the Son. Concerning the Holy Spirit, we believe thus: divine Spirit, holy Spirit, perfect Spirit, Paraclete, uncreated, speaking in the Law and the Prophets and the Apostles, and descending upon the Jordan. Concerning the incarnation of the Son from the Virgin, we believe thus: that he assumed a perfect man from the Theotokos Mary through the Holy Spirit, body and soul, truly and not in appearance; for thus he came to perfect the man whom he assumed.

and that he suffered, and that he was buried, and that he rose on the third day, and that he was taken up into heaven and sat down at the right hand of the Father, deifying the man whom he assumed, coming to judge the living and the dead according to the foreknowledge from God. But if the divine scriptures speak of him in a proleptic manner as a creature, we understand that to be fulfilled in respect to the flesh. Furthermore, we anathematize those who do not confess the resurrection of the flesh and all heresies contrary to this faith. The godless faith of the Arians was also anathematized in what was previously written, in that we believe and say: begotten, not made. For they say that the Son of God is a creature. And to complete all the parts of the faith, we confess and say: that we believe in one church, in one baptism, in the resurrection of the flesh, in the kingdom of heaven, in eternal judgment.
