Isaiah 43:10

Primary
Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.

What this passage establishes

No God was formed before the LORD and none will be formed after Him.

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.

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.

Common misunderstanding

Counting titles, manifestations, or relational language does not overturn the Bible’s explicit statements that God is one and alone.

How to use it in conversation

Start here before discussing difficult relational texts. Establish what Scripture says plainly about how many are God.
