For God is not the author of confusion, but of peace, as in all churches of the saints.

No. The modern woke "versions" changed the "Holy Ghost" to "Holy Spirit", but changing the Word of God is never a good idea. The proof is here on this site, Saved.Church.

Ask anyone (including your pastor) why the "versions" of the Bible changed Holy Ghost to Holy Spirit and many will say because the King James is too hard. That means you need a teacher. 

God is the Word, and the Word says there will be teachers in the Church. The teachers must teach, but not all people claiming to be teachers use the King James Bible as they should.

• And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. Are all apostles? are all prophets? are all teachers? are all workers of miracles? 1 Corinthians 12:28-29.
• And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ: That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; Ephesians 4:11-14.

Yes. The term “Holy Ghost” is used 89 times in the New Testament of the King James Bible. "Holy Spirit" is used four times in some form. The term “Holy Spirit” is used once, and the term "holy Spirit" is used three times. The context of every use is significant, and don't forget that the Word is timeless. (Underlining emphasis is added to the text below.)

Jesus used the term Holy Spirit to describe the entire Spirit of God as the good gifts from the Father, the origin of the Holy Spirit of God. The term wasn't used to limit the context to the Holy Ghost, or the term Holy Ghost would have been used. See John 7:39.

• If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him? Luke 11:13. 

Paul the apostle used "holy" as an adjective. The use is not limited to the Holy Ghost.

• For God hath not called us unto uncleanness, but unto holiness. He therefore that despiseth, despiseth not man, but God, who hath also given unto us his holy Spirit. 1 Thessalonians 4:7-9.
• [Interlinerated for clarity] In whom [Jesus] also we have obtained an inheritance, being predestinated according to the purpose of him [the Father] who worketh all things after the counsel of his own will [the Father's will we come to know by the Holy Ghost]: That we [the born again of that holy Spirit of promise] should be to the praise of his glory, who first trusted in Christ. In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise [the Word and the Holy Ghost], Which is the earnest of our inheritance [sonship by the Spirit as a chosen of God the Father, the essence of the promise] until the redemption of the purchased possession [the saved individuals], unto the praise of his glory [to dwell forever in the kingdom of His counsel called Heaven]. Ephesians 1:11-14. [Interlineated for clarity].
• And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. Ephesians 4:30.

No. "Holy Spirit" can mean the Father, the Word, the Holy Ghost, and any combination of the three. The Holy Ghost means the Holy Ghost, the Spirit of Truth. Changing the Holy Ghost to the Holy Spirit causes confusion.

Reproof: If the versions can change “Holy Ghost” to “Holy Spirit” as if they were interchangeable, what about changing the one occurrence of “Holy Spirit” and the three instances of "holy Spirit" to “Holy Ghost”? If we made those four changes, the Word would change significantly because the context of the above verses would incorrectly limit the Spirit only to the context of the Holy Ghost (the Spirit of Truth).

Result: Confusion results from changing the Holy Ghost to the Holy Spirit.

• For God is not the author of confusion, but of peace, as in all churches of the saints. 1 Corinthians 14:33.

Changing the Word of God corrupts it, causing confusion and quenching of the Spirit. 

• Quench not the Spirit. 1 Thessalonians 5:19.

Webster's 1828 dictionary defines "Quench" as: "1. To extinguish; to put out; as, to quench flame. 2. To still; to quiet; to repress; as, to quench a passion or emotion.

3. To allay or extinguish; as, to quench thirst. 4. To destroy. 5. To check; to stifle; as, to quench the Spirit. 1 Thessalonians 5:19."

In all circumstances involving a "version" other than the Bible, the King James, please use your version alongside the King James Bible. A digital copy is provided below if you need one.

Why? Your New Testament cannot be reconciled using only the words in it. Even worse, if it removed the term Holy Ghost as written in the Bible, it will never directly teach you how the Father wants to communicate with you as an individual. 

The Holy Ghost is the way we come to know the Father on earth. The enemy has tried to hide that fact by seducing men to change the Word for money, power, prestige, fame, influence, etc.; all the fleshly stuff the enemy uses to tempt people to sin.

Think of it this way: were the authors of the "versions" really led by God to change His Word and, in some cases, hide Him from us by removing the references to the Holy Ghost? Did mankind think He could improve the Word they thought was insufficient?
