In his excellent book on theosis and the Latter-day Saint conception of God, D. Charles Pyle wrote the following refuting the concept that the Father, Son, and Spirit are “consubstantial” as understood by traditional Trinitarian understandings of that term:
The following scriptures also further strengthen the LDS viewpoint that the Father, Son, and Holy Spirit, aren’t literally consubstantial in the metaphysical sense claimed of the three:
v 1 Corinthians 6:17 (he that is joined to the Lord is one spirit . . .)
v 1 Corinthians 3:6, 8 (Paul [who planted] and Apollos [who watered] are one).
v Matthew 12:32 (whoever speaks against the Son will be forgiven; those who speak against the Holy Ghost will not be forgiven [thus not consubstantial])
v John 8:16-18, 42 (the father and Son are two men who bear witness of Jesus; Jesus with and sent by the Father).
v Luke 18:18-19 (Jesus denies being the same God as his Father by excluding himself).
v Mark 13:32 (Jesus does not know what the Father knows; impossible if they ontologically are the same Being).
v Hebrews 9:24 (Jesus now is in the presence of God for us; the symbolism here is that of Jesus being our High Priest, requiring a separate personage from God).
v Acts 7:55-56 (Father and Son are seen as two separate personages by Stephen; Son on right side of God).
v Zechariah 13:7 (The Father and son are fellows [to be one’s fellow one must be separable from the other]; the Hebrew word there, עָמִית, from the root meaning “to associate,” representing individuals of like nature and being, and emphasizes in this verse [as the same word does in Leviticus 19:17, though translated “neighbor” in the KJV] separateness of the being of the shepherd from the One speaking. Thus the mighty man spoken of here is a fellow or kindred God besides God who speaks in the passage).
v Revelation 3:11-12, 14 (Jesus’ Father is his God, and Jesus is the beginning of the creation of God [both being impossible if he is the same God in the sense that the critics want Latter-day Saints to believe that he is]) (D. Charles Pyle, I Have Said Ye Are Gods: Concepts Conducive to the Early Christian Doctrine of Deification in Patristic Literature and the Underlying Strata of the Greek New Testament (Revised and supplemented) [CreateSpace, 2018], 155-56, emphasis in original)
