“The Father and I Are One”
Doctrine and Covenants 93:3–5
3 And that I am in the Father, and the Father in me, and the Father and I are one—
4 The Father because he gave me of his fulness, and the Son because I was in the world and made flesh my tabernacle, and dwelt among the sons of men.
5 I was in the world and received of my Father, and the works of him were plainly manifest.
Elder Bruce R. McConkie wrote:
“The Father and the Son are one. They have the same character, perfections, and attributes. They think the same thoughts, speak the same words, perform the same acts, have the same desires, and do the same works. They possess the same power, have the same mind, know the same truths, live in the same light and glory. To know one is to know the other; to see one is to see the other; to hear the voice of one is to hear the voice of the other. Their unity is perfect.”
(The Promised Messiah: The First Coming of Christ [1978], 9.)
