In the Douay-Rheims Old Testament the term Holy Spirit (or holy spirit) occurs just 4 times. We know now that it could not have been a conscious matter of the human author to be referring to the Third Person of the Blessed Trinity because at that time, the dogma of the Blessed Trinity had not yet been revealed. That wouldn't happen until the Second Person taught the Apostles.

Here are the 4 places:

1  100%  "Cast me not away from thy face; and take not thy holy spirit from me." [Psalms 50:13]

2  100%  "For the Holy Spirit of discipline will flee from the deceitful, and will withdraw himself from thoughts that are without understanding, and he shall not abide when iniquity cometh in."  [Wisdom 1:5]

3 100%  "And who shall know thy thought, except thou give wisdom, and send thy Holy Spirit from above:"  [Wisdom 9:17]

St. Ambrose

On the Holy Spirit (Book I)

Chapter 4.

The Holy Spirit is one and the same Who spoke in the prophets and apostles, Who is the Spirit of God and of Christ; Whom, further, Scripture designates the Paraclete, and the Spirit of life and truth.

55. But no one will doubt that the Spirit is one, although very many have doubted whether God be one. For many heretics have said that the God of the Old Testament is one, and the God of the New Testament is another. But as the Father is one Who both spoke of old, as we read, to the fathers by the prophets, and to us in the last days by His Son; Hebrews 1:1-2 and as the Son is one, Who according to the tenour of the Old Testament was offended by Adam, Genesis 3:17 seen by Abraham, Genesis 18:22-23 worshipped by Jacob; Genesis 28:17 so, too, the Holy Spirit is one, who energized in the prophets, 2 Peter 1:21 was breathed upon the apostles, John 20:22 and was joined to the Father and the Son in the sacrament of baptism. Matthew 28:19 For David says of Him: "And take not Your Holy Spirit from me." And in another place he said of Him: "Whither shall I go from Your Spirit?"

56. That you may know that the Spirit of God is the same as the Holy Spirit, as we read also in the Apostle: "No one speaking in the Spirit of God says Anathema to Jesus and no one can say, Lord Jesus, but in the Holy Spirit," 1 Corinthians 12:3 the Apostle calls Him the Spirit of God. He called Him also the Spirit of Christ, as you read: "But you are not in the flesh but in the Spirit, if so be that the Spirit of God dwells in you." Romans 8:9 And farther on: "But if the Spirit of Him Who raised Jesus from the dead dwells in you." Romans 8:11 The same is, then, the Spirit of God, Who is the Spirit of Christ.

57. The same is also the Spirit of Life, as the Apostle says: "For the law of the Spirit of Life in Christ Jesus has delivered me from the law of sin and death." Romans 8:2

58. Him, then, Whom the Apostle called the Spirit of Life, the Lord in the Gospel named the Paraclete, and the Spirit of Truth, as you find: "And I will ask the Father, and He will give you another Comforter [Paraclete], that He may be with you for ever, even the Spirit of Truth, Whom this world cannot receive; because it sees Him not, neither knows Him." John 14:16-17 You have, then, the Paraclete Spirit, called also the Spirit of Truth, and the invisible Spirit. How, then, do some think that the Son is visible in His Divine Nature, when the world cannot see even the Spirit?

59. Receive now the saying of the Lord, that the same is the Holy Spirit Who is the Spirit of Truth, for you read in the end of this book: "Receive the Holy Spirit." John 20:22 And Peter teaches that the same is the Holy Spirit Who is the Spirit of the Lord, when he says: "Ananias, why has it seemed good to you to tempt and to lie to the Holy Spirit?" Acts 5:3 And immediately after he says again to the wife of Ananias: "Why has it seemed good to you to tempt the Spirit of the Lord?" Acts 5:9 When he says "to you," he shows that he is speaking of the same Spirit of Whom he had spoken to Ananias. He Himself is, then, the Spirit of the Lord Who is the Holy Spirit.

60. And the Lord Himself made clear that the same Who is the Spirit of the Father is the Holy Spirit, when according to Matthew He said that we ought not to take thought in persecution what we should say: "For it is not you that speak, but the Spirit of your Father that speaks in you." Matthew 10:20 Again He says according to St. Luke: "Be not anxious how you shall answer or speak, for the Holy Spirit of God shall teach you in that hour what you ought to say." Luke 12:11-12 So, although many are called spirits, as it is said: "Who makes His Angels spirits," yet the Spirit of God is but one.

61. Both apostles and prophets received that one Spirit, as the vessel of election, the Doctor of the Gentiles, says: "For we have all drunk of one Spirit;" 1 Corinthians 12:13 Him, as it were, Who cannot be divided, but is poured into souls, and flows into the senses, that He may quench the burning of this world's thirst.

St. Augustine

Letter 185

50. But those with whom we are arguing, or about whom we are arguing, are not to be despaired of, for they are yet in the body; but they cannot seek the Holy Spirit, except in the body of Christ, of which they possess the outward sign outside the Church, but they do not possess the actual reality itself within the Church of which that is the outward sign, and therefore they eat and drink damnation to themselves. 1 Corinthians 11:29 For there is but one bread which is the sacrament of unity, seeing that, as the apostle says, "We, being many, are one bread, and one body." 1 Corinthians 10:17 Furthermore, the Catholic Church alone is the body of Christ, of which He is the Head and Saviour of His body. Ephesians 5:23 Outside this body the Holy Spirit gives life to no one seeing that, as the apostle says himself, "The love of God is shed abroad in our hearts by the Holy Ghost which is given unto us;" Romans 5:5 but he is not a partaker of the divine love who is the enemy of unity. Therefore they have not the Holy Ghost who are outside the Church; for it is written of them, "They separate themselves being sensual, having not the Spirit." Jude 19 But neither does he receive it who is insincerely in the Church, since this is also the intent of what is written: "For the Holy Spirit of discipline will flee deceit." Wisdom 1:5 If any one, therefore, wishes to receive the Holy Spirit, let him beware of continuing in alienation from the Church, let him beware of entering it in the spirit of dissimulation; or if he has already entered it in such wise, let him beware of persisting in such dissimulation, in order that he may truly and indeed become united with the tree of life.

St. Augustine

On the Trinity (Book III)


21.

(. . .)

"And Your counsel who has known, except Thou give wisdom, and send Your Holy Spirit from above;" therefore we refrain indeed from searching out the things which are in heaven, under which kind are contained both angelical bodies according to their proper dignity, and any corporeal action of those bodies; yet, according to the Spirit of God sent to us from above, and to His grace imparted to our minds, I dare to say confidently, that neither God the Father, nor His Word, nor His Spirit, which is the one God, is in any way changeable in regard to that which He is, and whereby He is that which He is; and much less is in this regard visible. Since there are no doubt some things changeable, yet not visible, as are our thoughts, and memories, and wills, and the whole incorporeal creature; but there is nothing that is visible that is not also changeable.

God have mercy, this nonsense is raising my blood pressure.

Mountain out of a mole hill.

Don't be too eager to put forward an argument wherein you may find yourself teetering into heresy.

"All change except away from evil, is the most dangerous of all things" (Plato)

Anyone that does not respect what came before him, will learn the hard way why it was done the way it was done.

Vernacular languages DO change.  And that kind of change could be good or bad or neutral.  It just happens with living languages.  That's why, when in doubt, go to the Latin.  And if the culture/language shifts away from the Church's standard, then the Church adapts.  Words can pick up negative connotations over time.  Take the word "gαy", for instance.  So you would fault the Church for changing a few vernacular translations in order to avoid phrases claiming that certain saints were "gαy" ... if for no other reason than to eliminate inappropriate chuckles from school kids?  In such cases, it's the language that changes and not the Church.  And the Church is constantly evaluating whether or not certain aspects of society are or are not in conformity with her own unchanging standards and principles.  So you have it completely backwards.  What doesn't change is the standard of the Church in judging culture and language.

Who taught you to use Holy Spirit?

Uhm, both terms appear in approved Catholic sources well before Vatican II.

I said nothing about Vatican II, I just simply asked: Who taught you to use Holy Spirit?

And the answer should have been evident in my post.  I have encountered both terms in approved books and over time developed a preference for Holy Spirit ... most likely due to it being closest to the Latin, since I generally pray in Latin.  This really isn't that difficult.
