Do you believe God required a sacrifice and that Christ was our substitution on the cross who paid our penalty?
"Do you believe God required a sacrifice and that Christ was our substitution on the cross who paid our penalty?"
Sort of depends on who was demanding what, HD. Here's an answer well within the consensus patrum from +Gregory Nazianzus:
"Now we are to examine another fact and dogma, neglected by most people, but in my judgment well worth enquiring into. To Whom was that Blood offered that was shed for us, and why was It shed? I mean the precious and famous Blood of our God and High priest and Sacrifice. We were detained in bondage by the Evil One, sold under sin, and receiving pleasure in exchange for wickedness. Now, since a ransom belongs only to him who holds in bondage, I ask to whom was this offered, and for what cause? If to the Evil One, fie upon the outrage! If the robber receives ransom, not only from God, but a ransom which consists of God Himself, and has such an illustrious payment for his tyranny, a payment for whose sake it would have been right for him to have left us alone altogether. But if to the Father, I ask first, how? For it was not by Him that we were being oppressed; and next, On what principle did the Blood of His Only begotten Son delight the Father, Who would not receive even Isaac, when he was being offered by his Father, but changed the sacrifice, putting a ram in the place of the human victim?68 Is it not evident that the Father accepts Him, but neither asked for Him nor demanded Him; but on account of the Incarnation, and because Humanity must be sanctified by the Humanity of God, that He might deliver us Himself, and overcome the tyrant, and draw us to Himself by the mediation of His Son, Who also arranged this to the honour of the Father, Whom it is manifest that He obeys in all things? So much we have said of Christ; the greater part of what we might say shall be reverenced with silence. But that brazen serpent was hung up as a remedy for the biting serpents, not as a type of Him that suffered for us, but as a contrast; and it saved those that looked upon it, not because they believed it to live, but because it was killed, and killed with it the powers that were subject to it, being destroyed as it deserved. And what is the fitting epitaph for it from us? "O death, where is thy sting? O grave, where is thy victory?" Thou art overthrown by the Cross; thou art slain by Him who is the Giver of life; thou art without breath, dead, without motion, even though thou keepest the form of a serpent lifted up on high on a pole."
This is a vulgar restatement of patristic theology of atonement. Were I speaking to a child, I would perhaps let it be, in hopes to correct him later in life. No, God definitely does not want a sacrifice, and the description of the mystery in these crude transactional terms is incorrect. It is also not what St. Anselm wrote. I will check with St. Anselm before getting into this further.
That is aliento Orthodoxy. Personally, it's blasphemous.
