1] Our Churches, with common consent, do teach that the decree of the Council of Nicaea concerning the Unity of the Divine Essence and concerning the Three Persons, is true and to be believed without any doubting; 2]that is to say, there is one Divine Essence which is called and which is God: eternal, without body, without parts, of infinite power, wisdom, and goodness, the Maker and Preserver of all things, visible and invisible; and 3] yet there are three Persons, of the same essence and power, who also are coeternal, the Father, the Son, and the Holy Ghost. And the term “person” 4] they use as the Fathers have used it, to signify, not a part or quality in another, but that which subsists of itself.
5] They condemn all heresies which have sprung up against this article, as the Manichaeans, who assumed two principles, one Good and the other Evil: also the Valentinians, Arians, Eunomians, Mohammedans, and all such.6] They condemn also the Samosatenes, old and new, who, contending that there is but one Person, sophistically and impiously argue that the Word and the Holy Ghost are not distinct Persons, but that “Word” signifies a spoken word, and “Spirit” signifies motion created in things.
Especially when in the first article they confess the unity of the divine essence in three persons according to the decree of the Council of Nice, their Confession must be accepted, since it agrees in all respects with the rule of faith and the Roman Church. For the Council of Nice, convened under the Emperor Constantine the Great, has always been regarded inviolable, whereat three hundred and eighteen bishops eminent and venerable for holiness of life, martyrdom and learning, after investigating and diligently examining the Holy Scriptures, set forth this article which they here confess concerning the unity of the essence and the trinity of persons. So too their condemnation of all heresies arising contrary to this article must be accepted – viz. the Manichaeans, Arians, Eunomians, Valentinians, Samosatanes, for the Holy Catholic Church has condemned these of old.
