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.

If... Adam had trusted in God and been nourished from the tree of life (Gn. 2:9)? he would not have set aside the immortality that had been granted. For such immortality is eternally preserved by participation in life, since all life is genuine and preserved by appropriate food. The food of that blessed life is 'the bread that came down from heaven and gives life to the world' (Jn. 6:33), just as the inerrant Word Himself declares about Himself in the Gospels.

Theology without practice is the theology of demons

When we think of the height of God's infinity we should not despair of His compassion reaching us from such a height; and when we recall the infinite depth of our fall through sin we should not refuse to believe that the virtue which has been killed in us will rise again. For God can accomplish both these things: He can come down and illumine our intellect with spiritual knowledge, and He can raise up the virtue within us and exalt it with Himself through works of righteousness.

When what has been created in time according to the temporal order has reached maturity, it ceases from natural growth. But when what has been brought about by the knowledge of God through the practice of the virtues has reached maturity, it starts to grow anew. For the end of one stage constitutes the starting point of the next.

If the words of God are uttered merely as verbal expressions, and their message is not rooted in the virtuous way of life of those who utter them, they will not be heard. But if they are uttered through the practice of the commandments, their sound has such power that they dissolve the demons and dispose men eagerly to build their hearts into temples of God through making progress in works of righteousness.

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.
