"I Believe in the Holy Ghost"
The Holy Ghost Is Equal To The Father And The Son
The people, when once acquainted with the meaning of His name, should first of all be taught that the Holy Ghost is equally God with the Father and the Son, equally omnipotent and eternal, infinitely perfect, the supreme good, infinitely wise, and of the same nature as the Father and the Son.
All this is obviously enough implied by the force of the word in, when we say: I believe in the Holy Ghost; for this preposition is prefixed to each Person of the Trinity in order to express the exact nature of our faith.
The Divinity of the Holy Ghost is also clearly established by many passages of Scripture. When, in the Acts of the Apostles, St. Peter says, Ananias, Why hast thou conceived this thing in thy heart? he immediately adds: Thou hast not lied to men, but to God, calling Him God to whom he had just before given the name Holy Ghost.
The Apostle, also, writing to the Corinthians, interprets what he says of God as said of the Holy Ghost. There are, he says, diversities of operations, but the same God, who worketh all in all; but, he continues, all these things one and the same Spirit worketh, dividing to every one according as he will.
In the Acts of the Apostles also what the Prophets attribute to God alone, St. Paul ascribes to the Holy. Ghost. Thus Isaias had said: I heard the voice of the Lord, saying: Whom shall I send? . . . And he said: Go, and thou shalt say to this people: Blind the heart of this people, and make their ears heavy, and shut their eyes, lest they see with their eyes, and hear with their ears. Having cited these words, the Apostle adds: Well did the Holy Ghost speak to our fathers, by Isaias the prophet.
Again, the Sacred Scriptures join the Person of the Holy Ghost to those of the Father and the Son, as, for example, when Baptism is commanded to be administered in the name of the Father, and of the Son, and of the Holy Ghost. There is thus no room left us of doubting the truth of this mystery. For if the Father is God, and the Son God, we must admit that the Holy Ghost, who is united with Them in the same degree of honour, is also God.
Besides, baptism administered in the name of any creature can be of no effect. Were you baptised in the name of Paul? says the Apostle, to show that such baptism could have availed nothing to salvation. Since, therefore, we are baptised in the name of the Holy Ghost, we must acknowledge the Holy Ghost to be God.
This same order of the Three Persons, which proves the Divinity of the Holy Ghost, is also found in the Epistle of St. John: There are three who give testimony in heaven, the Father, the Word, and the Holy Ghost, and these three are one; and also in that noble eulogy of the Holy Trinity, with which the Divine Praises and the Psalms are concluded: Glory be to the Father, and to the Son, and to the Holy Ghost.
Finally, what most strongly confirms this truth is the fact that Holy Scripture assigns to the Holy Ghost whatever attributes we believe proper to God. Wherefore to Him is ascribed the honour of temples, as when the Apostle says: Know you not that your members are the temple of the Holy Ghost? Scripture also attributes to Him the power to sanctify, to vivify, to search the depths of God, to speak by the Prophets, and to be present in all places, all of which can be attributed to God alone.
