To Us There Is One God (the Father) and One Lord, Who Is Christ
1 Corinthians 8:5–6
5 For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
6 But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
The Prophet Joseph Smith said:
“The Apostles have discovered that there were Gods above, for Paul says God was the Father of our Lord Jesus Christ. My object was to preach the scriptures, and preach the doctrine they contain, there being a God above, the Father of our Lord Jesus Christ. I am bold to declare I have taught all the strong doctrines publicly, and always teach stronger doctrines in public than in private. . . .
“Paul says there are Gods many and Lords many. I want to set it forth in a plain and simple manner; but to us there is but one God—that is pertaining to us; and He is in all and through all. But if Joseph Smith says there are Gods many and Lords many, they cry, ‘Away with him! Crucify him! crucify him!’
“. . . Search the scriptures, for they testify of things that these apostates would gravely pronounce blasphemy. Paul, if Joseph Smith is a blasphemer, you are. I say there are Gods many and Lords many, but to us only one, and we are to be in subjection to that one, and no man can limit the bounds or the eternal existence of eternal time. . . .
“Some say I do not interpret the scripture the same as they do. They say it means the heathen’s gods. Paul says there are Gods many and Lords many; and that makes a plurality of Gods, in spite of the whims of all men. Without a revelation, I am not going to give them the knowledge of the God of heaven. You know and I testify that Paul had no allusion to the heathen gods. I have it from God, and get over it if you can. I have a witness of the Holy Ghost, and a testimony that Paul had no allusion to the heathen gods in the text.”
