“Weakness and mortality, which were not sin, but the penalty of sin, were undergone by the Redeemer of the World in the way of punishment, that they might be reckoned as the price of redemption. What therefore in all of us is the heritage of condemnation, is in Christ ‘the mystery of godliness.’ For being free from debt, He gave Himself up to that most cruel creditor.” (Leo the Great, Sermons 72.2)
