The Mormon "scripture" Book of Abraham does this same thing...as I believe the Book of Mormon does as well...
Here's an example: Moses 7:11: "And he gave unto me a commandment that I should baptize in the NAME of the Father, and of the Son, which is full of grace and truth, and of the Holy Ghost, which beareth record of the Father and the Son."
What's interesting when you read a Mormon General authority commentary on the Pearl of Great Price (Pearl of Great Price Commentary, Milton R. Hunter, Bookcraft, 1952/1971, pp. 52-53...Hunter cites this verse and prefaces it with:
* "The three Gods constituted the Holy Trinity" (p. 52)
* "...all three of these personages are one in purpose and unity; and they constitute the Holy Trinity" (p. 54)
Sandwiched in between those two comments, Hunter quotes Moses 5:6-9 and 7:11...and uses the heading that's in the Book of Abraham right before v. 11: "God's commandment to Enoch, and the Trinity"
You see, Mormons will use "the Trinity" like this to sound Christian to potential proselytes and for PR/image purposes...but when we get into more nitty-gritty discussions like those on FR, we get Mormons like yourself and Teppe who come out of the woodwork to diss "the Trinity." IoW, the real teeth are bared!
Hence, Mormons have their own "pseudo-'trinity'" -- what they more commony reference as "the Godhead."
Mormons and Christians all believe in "three persons"...Mormons just don't want to seem to concede that these three Persons are more unified than simply in "purpose and unity." Hey, Christians and Mormons alike are more unified with their spouses than simply "purpose and unity"...Hence, LdsISM has the untenable position of defending a "godhead" whose unity is even less unified than any mortal marriage committed in Christ's Name!
Simply wow!
Going outside the Bible for references unique to you and your beliefs is unfair. I do not know the author or the book.
I’ll discuss anything in the Holy Bible with you, but not your other sources, documented or not. I have no interest in doing so.
