If I understand correctly, where we believe the Father, Son and Holy Spirit are three persons making up the
one and only tri-une God, Joseph Smith, the founding prophet of Mormonism taught they were three persons making up
three separate gods: (the Bible says there is only one God)
Joseph Smith's Sermon on Plurality of Gods
(as printed in History of the Church, Vol. 6, p. 473-479)
SERMON BY THE PROPHETTHE CHRISTIAN GODHEADPLURALITY OF GODS.
Meeting in the Grove, east of the Temple, June 16, 1844.
Prayer by Bishop Newel K. Whitney.
Choir sang, "Mortals Awake."
President Joseph Smith read the 3rd chapter of Revelation, and took for his text 1st chapter, 6th verse"And hath made us kings and priests unto God and His Father: to Him be glory and dominion forever and ever. Amen.
...I will preach on the plurality of Gods. I have selected this text for that express purpose. I wish to declare I have always and in all congregations when I have preached on the subject of the Deity, it has been the plurality of Gods. It has been preached by the Elders for fifteen years.
I have always declared God to be a distinct personage, Jesus Christ a separate and distinct personage from God the Father, and that the Holy Ghost was a distinct personage and a Spirit: and these three constitute three distinct personages and three Gods. If this is in accordance with the New Testament, lo and behold! we have three Gods anyhow, and they are plural: and who can contradict it!...
