Ambrose of Milan (339-397), Flight from the World

The Fathers of the Church, vol. 65, trans. M. P. McHugh (Washington, DC: Catholic University of America Press, 1972), ch. 7, sect. 44, pp. 314–315.

And so then, Jesus took flesh that He might destroy the curse of sinful flesh, and He became for us a curse that a blessing might overwhelm a curse, uprightness might overwhelm sin, forgiveness might overwhelm the sentence, and life might overwhelm death. He also took up death that the sentence might be fulfilled and satisfaction might be given for the judgment, the curse placed on sinful flesh even to death. Therefore, nothing was done contrary to God’s sentence when the terms of that sentence were fulfilled, for the curse was unto death but grace is after death.
