Unclean spirits increase the passions in us, making use of our negligence, and inciting them. But the angels decrease our passions, inciting us to the perfection of virtue.

A passion is a contranatural movement of the soul or an irrational love, or an blindfold hatred toward any material thing, or because of it: for example, for food, or for women, or for riches, or for worldly glory, or any other sensible thing; or for the sake of such things, as in a senseless hatred for someone on account of the things mentioned above.

There are lots of those who speak but few who do. However, no one should distort the word of God by his own negligence, but it is better to confess your own weakness, not hiding the truth of God, so that together with the breaking of the commandments you do not also appear guilty of an untrustworthy explanation of the word of God.

If an unexpected temptation comes, don't blame the one through whom it came, but seek out the reason. Thus you will find correction for your soul.

Christianity is an entirely new way of being human.

Do not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: "The demons also believe and tremble" (James, 2:19). The action of love consists in heartfelt good deeds toward one's neighbor, magnanimity, patience, and sober use of things.

When our intellect has shaken off its many opinions about created things, then the inner principle of truth appears clearly to it, providing it with a foundation of real knowledge and removing its former preconceptions as though removing scales from eyes, as happened in the case of St. Paul (cf. Acts 9:18). For an understanding of Scripture that does not go beyond the literal meaning, and a view of the sensible world that relies exclusively on sense perception, are indeed scales, blinding the soul's visionary faculty and preventing access to the pure Logos of truth.
