Again, in that last solemn interview with His apostles on the night of the betrayal, the Lord Jesus thus cheered with sublime assurance their sorrowful despair: "But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me." (John 15:26.) Could the members of the Trinity be more definitely segregated? That the Comforter is the Holy Ghost is expressly set forth in the preceding chapter (John 14:26), and in that passage also the Father and the Son are as separately specified. That the Eternal Father and His Son Jesus Christ are individual Personages is clear from the very fact of the relationship expressed, for no being can be his own father or his own son. The numerous Scriptures in which Christ is shown as praying to His Father abundantly testify of Their distinct personality; and, furthermore, amidst the indescribable glory of our Lord's transfiguration, from out of the cloud came the voice of the Father, avowing again: "This is my beloved Son." The individual members of the Holy Trinity are united in purpose, plan, and method. To conceive of disagreement, differences, or dissension among them would be to regard them as lacking in the attributes of perfection that characterize Godhood. But that this unity involves any merging of personality is nowhere attested in Scripture, and the mind is incapable of apprehending such a union. In the course of His soulful High-Priestly prayer, Christ supplicated the Father in behalf of the Apostles, asking "that they may be one" as He and the Father were one (John 17:11). Surely the Lord did not intimate that He would have the Apostles lose their individuality and become one person; and indeed, He had long before assured them that at a time which is even yet future they "shall sit upon twelve thrones, judging the twelve tribes of Israel." (Matt. 19:28.) Human knowledge concerning the attributes of God and the nature of the Godhead is such as has been revealed from the heavens. Divine revelation is the ultimate source of all we know of the being and personality of the Deity. Through revelation in ancient days God was made known to man--to Adam, Enoch, Noah, Abraham, Moses, and the prophets. And in the present age, after mankind had in great measure come to reject the plain and simple truths of a personal God and His actual Son Jesus Christ, such as the Scriptures affirm, the Father and the Son have revealed Themselves anew. Joseph Smith has given us his solemn testimony that in the early spring of 1820, while engaged in solitary prayer, to which he had been impelled by scriptural admonition (James 1:5), he was visited by the Eternal Father and His Son Jesus Christ, and that the Father, pointing to the Christ, spake, saying: "This is my beloved Son, hear Him."
