How about the strongest points of my argument for starters. Luke 2:52 52 And Jesus increased in wisdom and stature, and in favour with God and man. If Jesus was perfected from the beginning, how could he increase in favour[sic] with God and Wisdom?
To hear-tell Stormie's view of this passage, he woulda thought that the diapered Jesus should have grabbed the nearest pulpit and proceeded to give his parents lectures on parenting.
Have you not read Phillippians 2?
5 In your relationships with one another, have the same mindset as Christ Jesus: 6 Who, being in very nature God, did not consider equality with God something to be used to his own advantage; 7 rather, he made himself nothing by taking the very nature of a servant, being made in human likeness. 8 And being found in appearance as a man, e humbled himself
The Son of God "made Himself" nothing; he took on a servant's posture -- being made in human likeness; he humbled Himself.
And when Jesus prayed to His Father in John 17, He wasn't simply uttering words that any person could utter because of some so-called notion of Mormon pre-existence: 5 And now, Father, glorify me in your presence with the glory I had with you before the world began.
Glory in the Bible means weighty...a similar thing we accord to say a Supreme Court whose made a weighty judgment. It conveys loftiness; majesty. Jesus was referencing a unique glory that only He, the Father, and the Holy Spirit shared.
And Mormons reduce it by attempting to say that "Oh, that's just something we all had in the pre-existence." (Much in the same way Mormon theology reduces Heavenly Father's sovereign Almighty uniqueness when it claims man is just as eternal past as Heavenly Father is)
