Augustine of Hippo

Let us all flee to Christ. Against sin let us appeal to God, the giver of freedom. Let us request to have ourselves put up for sale that we may be redeemed by his blood. For the Lord says, "You were sold for nothing, and without money you shall be redeemed." That is, without payment, without your payment, because by mine. The Lord says this, for he gave the payment himself, not silver but his own blood. For we had remained both slaves and in need.
