Whoever would be saved must first of all take care that he hold the catholic faith. Which, except a man preserve whole and inviolate, he shall without doubt perish eternally. But this is the catholic faith, that we worship one God in trinity, and trinity in unity. Neither confounding the persons nor dividing the substance. For the person of the Father is one; of the Son, another; of the Holy Spirit, another. But the divinity of the Father, and of the Son, and of the Holy Spirit, is one, the glory equal, the majesty equal. Such as is the Father, such also is the Son, and such the Holy Spirit. The Father is uncreated, the Son is uncreated, the Holy Spirit is uncreated. The Father is infinite, the Son infinite, the Holy Spirit infinite. The Father is eternal, the Son eternal, and the Holy Spirit eternal. And yet, there are not three eternal beings, but one eternal being. As also there are not three uncreated beings, nor three infinite beings, but one uncreated and one infinite being. In like manner, the Father is omnipotent, the Son omnipotent, and the Holy Spirit omnipotent. And yet, there are not three omnipotent beings, but one omnipotent being. Thus the Father is God, the Son, God and the Holy Spirit, God. And yet there are not three Gods, but one God only. The Father is Lord, the Son, Lord, and the Holy Spirit, Lord. And yet, there are not three Lords, but one Lord only. For as we are compelled by Christian truth to confess each person distinctively to be both God and Lord, we are prohibited by the catholic religion to say that there are three Gods, or three Lords. The Father is made by none, nor created, nor begotten. The Son is from the Father alone, not made, not created, but begotten. The Holy Spirit is not created by the Father and Son, nor begotten, but proceeds. Therefore, there is one Father, not three Fathers; one Son, not three Sons; one Holy Spirit, not three Holy Spirits. And in this trinity there is neither prior or posterior, nothing greater or lesser, but all three persons are co-eternal and co-equal to themselves. So that through all, as was said above, both unity in trinity and trinity in unity is to be adored. Whoever therefore would be saved, let him thus think concerning the trinity.
