After having discussed the “doctrine of Christ,” the gospel, Nephi wrote: “And now, behold, my beloved brethren, this is the way; and there is none other way nor name given under heaven whereby man can be saved in the kingdom of God.
And now, behold, this is the doctrine of Christ, and the only and true doctrine of the Father, and of the Son, and of the Holy Ghost, which is one God, without end. Amen. ” (2 Nephi 31:21; italics added.)
In speaking of resurrected beings, Amulek explained that they “shall be brought and be arraigned before the bar of Christ the Son, and God the Father, and the Holy Spirit, which is one Eternal God, to be judged according to their works, whether they be good or whether they be evil” (Alma 11:44; italics added; cf. Mormon 7:7).
The verity of verities is that the members of the Eternal Godhead are one. To be judged of one is to be judged of all; to be blessed of one is to be blessed of all. And further, as explained earlier, Father and Son, Spirit and flesh, are brought together in one to form the “one God” who is the very Eternal Father of heaven and earth-Jesus Christ.
