Determinate will

Eusebius of Nicomedia, ally of Arius, denied that we can infer anything about God from what has been created.  On one hand “there is God” while on the other “things created by free will.”  The Word is also a creature of the free will of God.  This free will is utterly undetermined.

For the orthodox, of course, the Word is the will of the Father, and so the will of the Father has an eternal determinate form in the Son.
