[Risky-Riskerdo]

God did not, therefore, compel Christ to die; but he suffered death of his own will...

Hmmm...it sounds as if what is being said here is that God the Father plan was based upon what the Son was willing to do of His own will. Is this correct?

That would be in agreement with Jesus oft repeated statement that He came to do the Will of the Father.

John 5:30

30 I can of Myself do nothing. As I hear, I judge; and My judgment is righteous, because I do not seek My own will but the will of the Father who sent Me.

My statement wasn’t clear. Anselm is saying that God the Father’s plan was essentially to acquiesce to the will of the Son, who agreed to do the Father’s will. The Father wanted a perfect sacrifice and Christ was willing to be the perfect sacrifice because God the Father wanted it. To put it in very primitive human terms; the Father said He wanted a perfect sacrifice and Christ said he would be that sacrifice.

I would suggest that the Father’s will was the death of the Son and the Son knew that was what God's (Father) will was and it was His (Son) will. There is no discussion. The will of the Father and the Son was one of the same. Your verse points that out.
