Confessions on the Trinity

Tomorrow is Trinity Sunday. I will preaching on the Trinity. Here are the main confessions and their sections on the Trinity. 

Belgic Confession (Continental Reformed)
Article 8: The Trinity

In keeping with this truth and Word of God we believe in one God, who is one single essence, in whom there are three persons, really, truly, and eternally distinct according to their incommunicable properties– namely, Father, Son, and Holy Spirit. The Father is the cause, origin, and source of all things, visible as well as invisible.  The Son is the Word, the Wisdom, and the image of the Father. The Holy Spirit is the eternal power and might, proceeding from the Father and the Son. Nevertheless, this distinction does not divide God into three, since Scripture teaches us that the Father, the Son, and the Holy Spirit each has his own subsistence distinguished by characteristics– yet in such a way that these three persons are only one God.  It is evident then that the Father is not the Son and that the Son is not the Father, and that likewise the Holy Spirit is neither the Father nor the Son.  Nevertheless, these persons, thus distinct, are neither divided nor fused or mixed together.  For the Father did not take on flesh, nor did the Spirit, but only the Son.  The Father was never without his Son, nor without his Holy Spirit, since all these are equal from eternity, in one and the same essence.  There is neither a first nor a last, for all three are one in truth and power, in goodness and mercy.

Thirty Nine Articles (Anglican)
Article I: Of faith in the Holy Trinity

There is but one living and true God, everlasting, without body, parts, or passions; of infinite power, wisdom, and goodness; the maker and preserver of all things both visible and invisible. And in unity of this Godhead there be three Persons, of one substance, power, and eternity; the Father, the Son, and the Holy Ghost.

Augsburg Confession (Lutheran)
Article I: Of God

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; 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 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” they use as the Fathers have used it, to signify, not a part or quality in another, but that which subsists of itself.

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. 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.

Westminster Confession of Faith (English Reformed)
Article II:Of God and the Holy Trinity 

1. There is but one only, living, and true God, who is infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions; immutable, immense, eternal, incomprehensible, almighty, most wise, most holy, most free, most absolute; working all things according to the counsel of his own immutable and most righteous will, for his own glory; most loving, gracious, merciful, long-suffering, abundant in goodness and truth, forgiving iniquity, transgression, and sin; the rewarder of them that diligently seek him; and withal, most just, and terrible in his judgments, hating all sin, and who will by no means clear the guilty.

2. God hath all life, glory, goodness, blessedness, in and of himself; and is alone in and unto himself all-sufficient, not standing in need of any creatures which he hath made, nor deriving any glory from them, but only manifesting his own glory in, by, unto, and upon them. He is the alone fountain of all being, of whom, through whom, and to whom are all things; and hath most sovereign dominion over them, to do by them, for them, or upon them whatsoever himself pleaseth. In his sight all things are open and manifest, his knowledge is infinite, infallible, and independent upon the creature, so as nothing is to him contingent, or uncertain. He is most holy in all his counsels, in all his works, and in all his commands. To him is due from angels and men, and every other creature, whatsoever worship, service, or obedience he is pleased to require of them.

3. In the unity of the Godhead there be three persons, of one substance, power, and eternity: God the Father, God the Son, and God the Holy Ghost: the Father is of none, neither begotten, nor proceeding; the Son is eternally begotten of the Father; the Holy Ghost eternally proceeding from the Father and the Son.
