All sacrifices are offerings to some god or other, so to whom did god offer up his son as a sacrifice?

That's a premise. In Christianity, sacrifice acquires another meaning. The Son sacrifices Himself as flesh (yet He's God), and thus transforms our understanding of sacrifice - it's no longer understood strictly as sacrifice of flesh on the altar to God. As everything in the NT - the old is incorporated and made anew without contradicting the OT. God of the NT and OT is the same but the context is different.

Christ doesn't sacrifices Himself to alleviate God the Father's anger caused by Adam disobeying Him (although such a belief in penal substitution is widely held by protestants). This is impossible because all persons of the Trinity share the same will and essence. The Son incarnates, becomes man and defeats death, so that man can gain eternal life and become like God (theosis).

If I sacrifice myself for the well-being of my loved ones, do I offer myself to a god?
