Gregory the Great

For this sacrifice doth especially save our souls from everlasting damnation, which in mystery doth renew unto us the death of the Son of God: who although being risen from death, doth not now die any more, nor death shall not any further prevail against him: yet living in himself immortally, and without all corruption, he is again sacrificed for us in this mystery of the holy oblation: for there his body is received, there his flesh is distributed for the salvation of the people: there his blood is not now shed betwixt the hands of infidels, but poured into the mouths of the faithful.
