“When God through His life-giving breath created the soul deiform and intellective. He did not implant in it anger and desire that are animal-like. But He did endow it with a power of longing and aspiration, as well as with a courage responsive to divine love. Similarly when God formed the body He did not originally implant in it instinctual anger and desire. It was only afterwards, through the fall, that it was invested with these characteristics that have rendered it mortal, corruptible and animal-like. For the body, even though susceptive of corruption, was created, as theologians will tell us, free from corruption, and that is how it will be resurrected.”
(St Gregory of Sinai,  ‘On Commandments’ in the Philokalia)
