So .... in your “Trinitarian” view of Christ ....
.......Jesus prays to himself?
Can he also communicate to himself when he talks/thinks ..... or does it have to be prayer?
Does he know that there are excellent medications available for his scizophrenia?
Not MY view
But Your three witnesses
Deal with that historical fact
Nephi seems to recognize a distinction between the Father and the Son. Christ witnesseth obedience unto the Father (2 Nephi 31:7), and keeps the commandments of the Father (2 Nephi 31:7-11). In Jacobs day, the righteous Nephites worshipped the Father in Christs name and saw the story of Father Abrahams attempted sacrifice of his Son Isaac as a similitude of God and his Only Begotten Son (Jacob 4:5-6), which strongly suggests that they are separate individuals. Other passages describe Jesus as in complete harmony with but still subordinate to his Father (3 Nephi 11:32-36). Jesus prays to the Father (3 Nephi 17:13-18; 19:19-34), is sent by the Father (3 Nephi 27:13), the Father introduces the Son (3 Nephi 11:3-7), the Father commands the Son (3 Nephi 15:16; 16:10), the Son like an advocate for the defense hold the righteous guiltless before his Father at the day of judgement (3 Nephi 27:16). Since the Father, the Son, and the Holy Ghost are all described in the Book of Mormon as separate and distinct individuals, they constitute one God or divine government which is unified in purpose, will, doctrine and testimony.
