Salmos 102:4-5
"For I forgot to eat my bread. At the sound of my groaning, my bones stuck to my flesh." I lost appetite for any food, and was completely bereft of my former good condition, my body being consumed by the wasting of discouragement; I am but skin and bones. The word of God, then, is our soul's bread: just as ordinary bread nourishes the body, so the word from heaven [nourishes] the soul's substance. In passing on the prayer, Christ said as much to the apostles, "Give us this day our daily bread." So whoever forgets to eat it, that is, to be active (action, after all, constituting the eating of the spiritual bread, as is clear from the saying of the Lord to the apostles, "Be active, not for the eating, which perishes, but for that which endures to life eternal"), this one's heart is stricken and dried up like hay. How does hay get stricken and dry up? When rain stops falling on it. As the heart, too, when suffering from a dearth of the word, is then stricken and dries up, the flower of virtue no longer has the strength to bloom. — COMMENTARY ON THE PSALMS 102:3
Salmos 102:27
Even in the case of our own soul, when we say that it cannot die, we do not predicate weakness of it, but we proclaim its capacity of immortality. And similarly when we confess the immutability, impassibility and immortality of God, we cannot attribute to the divine nature change, passion or death. Suppose they insist that God can do whatever he will, you must reply to them that he wishes to do nothing that it is not his nature to do. He is good by nature; therefore he does not wish anything evil. He is just by nature; therefore he does not wish anything unjust. He is true by nature; therefore he considers falsehood abominable. He is by nature immutable; therefore he does not admit of change. If he does not admit of change, he is always in the same state and condition. This he himself asserts through the prophet: "I am the Lord; I change not." And the blessed David says, "You are the same, and your years shall have no end." If he is the same, he undergoes no change. If he is naturally superior to change and mutation, he has not become mortal from immortal or passible from impassible, for had this been possible he would not have taken on him our nature. But since he has an immortal nature, he took a body capable of suffering, and with the body a human soul. Both of these he kept unstained from the defilements of sin and gave his soul for the sake of the souls that had sinned and his body for the sake of the bodies that had died. And since the body that was assumed is described as the body of the very only-begotten Son of God, he refers the passion of the body to himself. — LETTER 144
