John 1:1
1In the beginning was the Word, and the Word was with God, and the Word was God.
John opens where Genesis opens, then names the One who was already there. Arminians confess with the whole church: the Word is God—supreme, eternal, independent. This is no created mind and no lesser deity.
The camps do not divide on the Trinity here. They will divide on how this Word is received. The eternity of the Son is shared ground; the later call to receive him is a serious invitation, not theater.
In the beginning was the Word: before time, with God, and God. The Evangelist asserts the eternal divinity of Christ so that faith in the Son is faith in the only God.
If the Word were not God, believing in him would be idolatry. The prologue will not let us treat Jesus as a gifted man who later became divine. He is the eternal God who will be manifested in flesh.
