Zechariah 14:9
And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
Primary
What this passage establishes
The kingdom hope culminates in one LORD and one name over all the earth.
Why it matters in the argument
This establishes the controlling biblical confession: every later passage about Father, Son, and Holy Ghost must be read without multiplying the one God. In Scripture, the divine name carries God’s identity, authority, presence, and saving action. The New Testament centers that saving revelation in Jesus.
Apostolic connection
Apostolic teaching begins with the Bible’s own insistence that God is one indivisible divine being, then reads the incarnation as that one God revealed in Christ. Jesus is not a competing name beside the Father; His name is the saving name in which the one God has made Himself known and acted for redemption.
Common misunderstanding
Counting titles, manifestations, or relational language does not overturn the Bible’s explicit statements that God is one and alone. Calling on Jesus’ name is not a verbal charm. It is an obedient appeal to His identity, authority, and saving work.
How to use it in conversation
Use this as a closing monotheism text: the final kingdom has one LORD and one name, not competing divine identities.
