The cross is where God is most fully and definitely revealed. We all agree about that. So whatever God is seen to be doing at the cross, will be core to his identity.
We say that the main thing happening at the cross is Penal Substitutionary Atonement. God punishing his son for sins we committed.
From the point of view of the Son, graciously ‘suffering for others’ is presumably revealed as core to his divine identity.
But for the Father, what is revealed? Here at the definite revealing of the Father, what do we see?
The infliction of punishment.
QUESTION: Is that really what we want to say about the core of God’s identity? If not, which bit of the above reasoning would we change?
