holy spirit, holy Spirit, Holy Spirit, or Holy Ghost - which is it?

A question few (very few) "christians" know the answer to: What is the difference between "Holy Spirit" and "Holy Ghost"

This is NOT as complicated as some extra smart Rev. Dr. will make it to be. But, it's like looking at an elephant under a microscope. First some framework, namely KJV and KJV only. Why? The translators of the KJV were as inspired by the "Holy Ghost" as any of the OT Prophets (I will come back to this). Now using a KJV that has all of the 500 or so typos corrected (not the original 1611), note the following:

The words "Holy Spirit", used just once (Luke 11:13). The words "holy Spirit" are used 5 times, twice in the OT and 3 times in the NT. The words "Holy Ghost"; 90 times, and all in the NT

Now for the Abomination that the overwhelming majority of "christians" use: the NIV; In the NIV; "holy Spirit" - ZERO! "Holy Ghost" - ZERO! "Holy Spirit" - 94 times; 3 times in the OT

An Ear Mark of a NT word #5569 ; they refer to the 3rd person of the God Head as "Holy Spirit". And contrary to what some Rev. Dr. ThD will professes, "Holy Spirit" and "Holy Ghost" are NOT interchangeable (Dale H Koller has stated this to me in writing)

Also; Strong's NT word # 4151 is used 388 times in the New Testament, sometimes translated "Ghost", sometimes "Spirit", sometimes "spirit". How did they know which one to use?...They were inspired by the Holy GHOST

How did I come to the conclusion that the Translators of the KJV were inspired? By doing a word study of one two letter word; "on" (NT word #1722). Used 2831 times in the NT. Sometimes translated "on", sometimes "in", sometimes "among", sometimes "with"...there are numerous English words used as a translation of this one Greek word "en"

An illustration of the importance of the difference between "on" and "in"; The Lord's Prayer (KJV - Matt 6:9, Luke 11:2) is it "on earth" or "in earth"? What's the difference?

I'm sure some extra smart (and holy) "Write Reverend" Dr. ThD DD will find fault with the above. Excuse me Rev. Dr. how did you acquire your pedigrees and accolades? Ohhh, you went to a prestigious seminary of the highest acclaim. Ohhh, is that so, what was your major? I see, "the sermon on the mount". Excuse me Rev. Dr, what was your thesis? Ohhh, the rituals for baking kosher bread of the Esenes. Ohhh, what was your dissertation? The Puritan concept of Buda in the 12th century...Excuse me Rev. Dr, in the vast amount of your study, did you ever read 1st John 2:20? Since you have abundantly demonstrated that this DOES NOT apply to you...take your Thd and your DD and use them to wipe your ass.
