New revelations regarding faith or morals ... have always been abhorred and challenged in the Church ... Hence, the Sovereign Pontiffs, the Councils, and the Fathers have been most careful to reject all novelties or new doctrines on matters of faith which differed from those already received.
Alphonsus LiguoriWhen we have to reply to anyone who has insulted us, we should be careful to do it always with gentleness. A soft answer extinguishes the fire of wrath.
Alphonsus LiguoriYou will gain more by receiving scorn peacefully than if you fasted for a week on bread and water. It is good to humble ourselves; but it is much more worthwhile to accept the humiliations that come to us from others.
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 LiguoriSaint Teresa, as the Roman Rota attests, never fell into any mortal sin; but still Our Lord showed her the place prepared for her in Hell; not because she deserved Hell, but because, had she not risen from the state of lukewarmness in which she lived, she would in the end have lost the grace of God and been damned.
