Holy Ghost and Holy Spirit

Are the "Holy Ghost" and the "Holy Spirit" the same? When Nephi refers to the "Holy Ghost" in 2 Ne. 33: 1, but then uses "Holy Spirit" in the next verse (2 Ne. 33: 2), does he have two different things in mind?

Joseph Smith defined the "Holy Spirit" as the "mind of the Father and Son" in the Lectures on Faith. Here is an excerpt:

There are two personages who constitute the great, matchless, governing and supreme power over all things--by whom all things were created and made, that are created and made, whether visible or invisible: whether in heaven, on earth, or in the earth, under the earth, or throughout the immensity of space--They are the Father and the Son: The Father being a personage of spirit, glory and power: possessing all perfection and fulness: The Son, who was in the bosom of the Father, a personage of tabernacle, made, or fashioned like unto man, or being in the form and likeness of man, or, rather, man was formed after his likeness, and in his image;--he is also the express image and likeness of the personage of the Father: possessing all the fulness of the Father, or, the same fulness with the Father; being begotten of him, and was ordained from before the foundation of the world to be a propitiation for the sins of all those who should believe on his name, and is called the Son because of the flesh--and descended in suffering below that which man can suffer, or, in other words, suffered greater sufferings, and was exposed to more powerful contradictions than any man can be. But notwithstanding all this, he kept the law of God, and remained without sin: Showing thereby that it is in the power of man to keep the law and remain also without sin. And also, that by him a righteous judgment might come upon all flesh, and that all who walk not in the law of God, may justly be condemned by the law, and have no excuse for their sins. And he being the only begotten of the Father, full of grace and truth, and having overcome, received a fulness of the glory of the Father-possessing the same mind with the Father, which mind is the Holy Spirit, that bears record of the Father and the Son, and these three are one, or in other words, these three constitute the great, matchless, governing and supreme power over all things: by whom all things were created and made, that were created and made: and these three constitute the Godhead, and are one: The Father and the Son possessing the same mind, the same wisdom, glory, power and fulness: Filling all in all--the Son being filled with the fulness of the Mind, glory and power, or, in other words, the Spirit, glory and power of the Father--possessing all knowledge and glory, and the same kingdom: sitting at the right hand of power, in the express image and likeness of the Father--a Mediator for man--being filled with the fulness of the Mind of the Father, or, in other words, the Spirit of the Father: which Spirit is shed forth upon all who believe on his name and keep his commandments: and all those who keep his commandments shall grow up from grace to grace, and become heirs of the heavenly kingdom, and joint heirs with Jesus Christ; possessing the same mind, being transformed into the same image or likeness, even the express image of him who fills all in all: being filled with the fulness of his glory, and become one in him, even as the Father, Son and Holy Spirit are one. (Lecture 5, Paragraph 2.)

The forgoing was published in 1835.

In a lecture given in 1843, Joseph stated the following (which can be found in D&C 130: 22):

The Father has a body of flesh and bones as tangible as man’s; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit. Were it not so, the Holy Ghost could not dwell in us.

If the Holy Ghost is a "personage of Spirit" and it can "dwell in us," and the Holy Spirit is "the mind of the Father and Son" then are they the same thing?

The scriptures have explained that the "Holy Ghost" which dwells in you - this personage of Spirit - has the following other descriptions, or attributes:
-the Comforter
-the record of heaven
-the truth of all things
-the peacable things of immortal glory
-that which quickeneth all things
-that which knoweth all things
-that which has all power according to wisdom, mercy, truth, justice and judgment.
(Moses 6: 61.)
This is a description of the personage of Spirit which dwells inside you. This is the Holy Ghost. This is something that can be in contact with the Holy Spirit, or the "mind of the Father and Son."

Perhaps you should look into this topic. Perhaps there is something to be found in this review.

There are many times when the term "Ghost" and the term "Spirit" are used interchangeably. The distinction is not appreciated by some translators. Therefore, if there is a difference between these two, you will need to be careful about trusting different translator's use of the terms. They may not have any distinction in mind.

If there is a difference, then what does that say about revelation? What does that say about you? And, keeping in mind yesterday's post, what does that say about 2 Ne. 33: 1-2?
