“Our whole nature had to be recalled from death to life. God therefore stooped over our dead body to offer His hand, so to speak, to the creature lying there. He came near enough to death to make contact with our mortal remains, and by means of His own body provided nature with the capacity for resurrection, thus by His power raising to life the whole of humanity… In our body the activity of any one of our senses communicates sensation to the whole of organism joined to that member. It is the same for humanity as a whole, which forms, so to speak, a single living being: The resurrection of one member extends to all, and that of a part to the whole, by virtue of the cohesion and unity of human nature.”
St. Gregory of Nyssa, Catechetical Orations, 32.
