§249From the beginning, the revealed truth of the Holy Trinity has been at the very root of the Church's living faith, principally by means of Baptism. It finds its expression in the rule of baptismal faith, formulated in the preaching, catechesis and prayer of the Church. Such formulations are already found in the apostolic writings, such as this salutation taken up in the Euchari…

§734Because we are dead or at least wounded through sin, the first effect of the gift of love is the forgiveness of our sins. the communion of the Holy Spirit126 in the Church restores to the baptized the divine likeness lost through sin.

§2627TWO fundamental forms express this movement: our prayer ascends in the Holy Spirit through Christ to the Father - we bless him for having blessed us;97 it implores the grace of the Holy Spirit that descends through Christ from the Father - he blesses us.98

2. This then is one way, and the first, by which he cast down their pride; the next has greater force. What then is this? In that he shows that not even this thing itself was in all points complete, but imperfect, and extremely so. And not only imperfect, but also injurious, unless there were another thing joined together with it. For having said that we have knowledge, he adde…

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. In the unity of the Godhead there be three Persons of one substance, power, and eternity: God the Father, God the Son, and God…

And in the Holy Ghost.

Q. Since there is but one God, why do you speak of three: Father, Son, and Holy Spirit? A. Because that is how God has revealed himself in his Word: these three distinct persons are one, true, eternal God.

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 ima…

All these things we know from the testimonies of Holy Scripture as well as from the effects of the persons, especially from those we feel within ourselves. The testimonies of the Holy Scriptures which teach us to believe in this Holy Trinity are written in many places of the Old Testament, which need not be enumerated but only chosen with discretion. In the book of Genesis God …

We believe in one God, true, almighty, and infinite, the Father, the Son, and the Holy Spirit; the Father unbegotten; the Son begotten of the Father before the ages, and consubstantial with Him; and the Holy Spirit proceeding from the Father, and consubstantial with the Father and the Son. These three Persons in one essence we call the All-Holy Trinity, by all creation to be ev…

We believe the three Persons of the Holy Trinity — the Father, the Son, and the Holy Spirit — to be one God, one in essence, and inseparable. The Father is altogether unbegotten and unoriginate; the Son is begotten of the Father before the ages; the Holy Spirit proceedeth from the Father, as from a fountain and cause. These are three Persons in one Godhead, equal in honor, in m…

We believe that there is one God, eternally existent in three persons: Father, Son and Holy Spirit.

The Lord our God is but one only living and true God, whose subsistence is in and of Himself, infinite in being and perfection. In this divine and infinite Being there are three persons, the Father, the Word or Son, and the Holy Spirit, of one substance, power, and eternity, each having the whole divine essence, yet the essence undivided.

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

Luther affirms the ecumenical doctrine of the Trinity as confessed in the Apostles', Nicene, and Athanasian Creeds: one God in three persons, coeternal and coequal. This article is not in dispute with Rome and stands as the foundation on which all other articles rest. Father, Son, and Holy Spirit — one divine essence, three distinct persons.

I believe in the Holy Spirit.

Neither confounding the persons nor dividing the substance. For there is one person of the Father, another of the Son, and another of the Holy Spirit. But the Godhead of the Father, of the Son, and of the Holy Spirit is all one, the glory equal, the majesty coeternal. Such as the Father is, such is the Son, and such is the Holy Spirit. The Father uncreated, the Son uncreated, t…

Tertullian declares that the Rule of Faith teaches one God who is nevertheless a Trinity — three Persons (personae) sharing one substance (substantia). He coins the term "trinitas" to describe this mystery. The divine monarchy is not abolished by recognizing the Son and Spirit, but is administered through them.

Basil insists that the Spirit is to be worshipped and glorified together with the Father and Son. The baptismal formula places the Spirit in the same rank of honor. The apostolic benediction names the Spirit alongside Father and Son as equal source of grace. To deny the Spirit worship is to deny His divinity.

Ambrose argues against those who deny the divinity of the Holy Spirit by reducing Him to a creature. The Spirit is worshipped and glorified together with the Father and the Son in the baptismal formula — "in the name of the Father, and of the Son, and of the Holy Spirit." If the Spirit were a creature, the Church would be commanding worship of a created being alongside the Crea…
