It is almost certain that excess in eating is the cause of almost all the diseases of the body, but its effects on the soul are even more disastrous.
Alphonsus LiguoriWe must practice modesty, not only in our looks, but also in our whole deportment, and particularly in our dress, our walk, our conversation, and all similar actions.
Alphonsus LiguoriTo obtain salvation we must tremble at the thought of being lost, and tremble not so much at the thought of hell, as of sin, which alone can send us thither. He who dreads sin avoids dangerous occasions, frequently recommends himself to God, and has recourse to the means of keeping himself in the state of grace. He who acts thus will be saved; but for him who lives not in this manner it is morally impossible to be saved.
Alphonsus LiguoriSt. 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.
