St. Augustine and St. Thomas define mortal sin to be a turning away from God: that is, the turning of one's back upon God, leaving the Creator for the sake of the creature. What punishment would that subject deserve who, while his king was giving him a command, contemptuously turned his back upon him to go and transgress his orders? This is what the sinner does; and this is punished in hell with the pain of loss, that is, the loss of God, a punishment richly deserved by him who in this life turns his back upon his sovereign good.
Alphonsus LiguoriIt would be the greatest delight of the seraphs to pile up sand on the seashore or to pull weeds in a garden for all eternity, if they found out such was God's will. Our Lord himself teaches us to ask to do the will of God on earth as the saints do it in heaven: "Thy will be done on earth as it is in heaven."
Alphonsus LiguoriHow, then, shall God give himself entirely to that one who, besides his God, loves creatures still?
Alphonsus LiguoriThere is nothing more pleasing to God, than to see a soul who patiently and serenely bears whatever crosses it is sent; this is how love is made, by putting lover and loved one on the same level. . . A soul who loves Jesus Christ desires to be treated the way Christ was treated-desires to be poor, despised and humiliated.
