Let us thank God for having called us to His holy faith. It is a great gift, and the number of those who thank God for it is small.
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.
Alphonsus LiguoriIn temptations against chastity, the spiritual masters advise us, not so much to contend with the bad thought, as to turn the mind to some spiritual, or, at least, indifferent object. It is useful to combat other bad thoughts face to face, but not thoughts of impurity.
Alphonsus LiguoriThe more a person loves God, the more reason he has to hope in Him. This hope produces in the Saints an unutterable peace, which they preserve even in adversity, because as they love God, and know how beautiful He is to those who love Him, they place all their confidence and find all their repose in Him alone.
