The Holy Ghost, we believe, is one of the characters that form the Trinity, or the Godhead. Not one person in three, nor three persons in one; but the Father, Son, and Holy Ghost are one in essence, as the hearts of three men who are united in all things. He is one of the three characters we believe in, whose office it is to administer to those of the human family who love the truth. I have stated that they are one, as the hearts of three men might be one. Lest you should mistake me, I will say that I do not wish you to understand that the Holy Ghost is a personage having a tabernacle, like the Father and the Son; but he is God's messenger that diffuses his influence through all the works of the Almighty. 6:95.

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.
