Isaiah 45:21

Primary
Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.

What this passage establishes

The just God and Savior declares that no God exists beside 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.
