I am obviously long-winded here but have much to mention

LDS have a problem reconciling a “properly translated” Bible to their system. Shocking to those who don’t know they equate Jesus Christ to be the brother of Satan. To take the lowly level of an fallen angel, elevate it to the level of the divine is absurd and a lie; The Roman Catholic Church has always asserted that Jesus is God. To be a Christian you must agree that Jesus Christ has a divine nature and is man and neither conflict; that is, Jesus Christ is GOD MADE MAN or the GOD-MAN. Anything less than that is a heresy and Truth is fragmenting. LDS believe Jesus had a good plan, Satan had a bad plan & the council of the Gods agreed to Jesus’ plan is how the man-made story goes.
A few verses to pray over:
the 7 I AM’s by Jesus in the Book of John
Jn 1:1 “… the Word was GOD”
Jn 8:58 “Before Abraham was, I AM”
Jn 20:28 “My Lord and my GOD”
Luke “… my spirit rejoices in GOD my Savior”
Hebrews 1:6 “let all God’s angels WORSHIP Him (Jesus)”

There is only ONE GOD - divine or otherwise.
Deut 6:4 The Schema states “Hear, O Israel: the Lord our God is one Lord.” The word they use is 'echad - one here means a unity of one: ex.1 bunch of grapes versus
yachid - one here means a solitude of one, ex. a single grape by itself. Hence, the Jews knew scripture hinted here that there was only 1 God. God himself clearly and plainly states He KNOWS OF NO OTHER - GODS that is.
Bottom line The Bible does not say TRINITY or Tri unity EXPLICITLY but the hints of it are jumping off the pages IMPLICITLY.
ex. of 11 day = morning, noon, evening, 1 family = father, mother, child

Scripture plainly says “there is no marriage in heaven” according to St. Paul
What is there to NOT understand about this very plain and straightforward scripture.
Jesus is the Bridegroom & the Church - all of us are the BRIDE. Jesus HAS ONLY 1 BRIDE, HE IS FAITHFUL TO THAT BRIDE - the CHURCH, NOT an ADULTERER = WHOLE BASIS FOR MARRIAGE = 1 man & 1 woman. period.
Not: 1 man & 2+ women or 6 women & 3 men or one Father & 2 Daughters or 1 man and 1 animal

Where does the fragmentation and the madness end.
These are only 3 thoughts; the LDS & ParkerD have a massive problem reconciling the Bible to their man-made system; I could list many more. Perhaps ParkerD and his cohorts would kindly consider obtaining a copy of the Catechism of the Catholic Church (CCC is a brilliant distillation of historic Christianity); would benefit by reading it, then line up what it plainly says against the quite latter-day system.
The next book would be “The Faith of the Early Fathers” by William Jurgens (3 volumes) & REALLY research & get the facts about WHAT REALLY HAPPENED instead of casually dismissing it as “apostasy”. That is sooo easy - many groups simply say the RCC is “apostate” obviously leaving out stacks and stacks of easily obtainable historic evidence for their review. Tragically, gross ignorance is abundant and lack of scholarship is showing.
A college prof of mine once said “Trust the evidence of your senses”
If one is fluent in German, could research The Funk-Bihlmeyer-Schneemelcher, “Die apostolischen Vater” volume 1. Tubingen 1956; “the Vienna Corpus” or the “Berlin Corpus”. Also, Migne’s "Patrologiae cursus completus, series latina (PL) for the Latin or series graeca (PG) for the Greek. Another is Kirsopp Lake “The Apostolic Fathers” in the Loeb Classical Library series (1930)
The first selection mentioned in Jurgens’ volume 1 is “The Didache or Teaching of the Twelve Apostles” circa AD 140 extant in the Codex Hierosolymitanus 1056 (11th century manuscript; The Didache has many earlier parts extant in Latin, Coptic, Ethiopic, Syriac, with complete translation in Georgian & Greek according to Jurgens). There are literally thousands of writings quoted in these sources that survive to this day to indicate essentially Christianity has been preserved INTACT from the early days to present times by God, the Father, Son and Holy Spirit and we believe as the early Christians believe.
(However, Tertullian did go 'round the bend later on.

To say otherwise is indefensible.
