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 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 LiguoriIn the Great Deluge in the days of Noah, nearly all mankind perished, eight persons alone being saved in the Ark. In our days a deluge, not of water but of sins, continually inundates the earth, and out of this deluge very few escape. Scarcely anyone is saved.
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.
