When Christ Himself spoke to Paul and called him, He could have opened his eyes at once and made known to him the way of perfection; instead He sent him to Ananias and told him to learn from him the way of truth, saying: 'Arise and go into the city, and there you will be told what you must do' (Acts 9:6). In this manner He teaches us to be guided by those who are advanced on the way, so that the vision rightly given to Paul should not be wrongly interpreted; otherwise it might lead later generations presumptuously to suppose that each individual must be initiated into truth directly by God, as Paul was, and not by the fathers.
For this world is opposed to the world above, and this present age to the eternity above. The Christian therefore, according to Holy Scripture, must deny the world, and be translated and pass in mind out of this present age, in which the mind is placed and exposed to allurements ever since the transgression of Adam, into another age, and in frame of thought must live in the world of the Godhead above, as it is said, But our conversation is in heaven. (Phil. iii. 20.).
Do not neglect the practice of the virtues; if you do, your spiritual knowledge will decrease, and when famine occurs you will go down into Egypt (Genesis 41:57, 46:6).
My brother, the passions are afflictions; and so the Lord does not excommunicate us because of them, but He says: 'Call upon me in the time of affliction; and I will deliver thee, and thou shalt glorify me'. Therefore, when beset by any kind of passion, there is nothing more useful than to call upon the Name of God. All we can do, weak as we are, is to flee for refuge to the Name of Jesus. For the passions, being demons, retreat if this Name is invoked.
A worker takes the trouble to get hold of the instruments that he requires. He does so not simply to have them and not use them. Nor is there any profit for him in merely possessing the instruments. What he wants is, with their help, to produce the crafted objective for which these are the efficient means. In the same way, fasting, vigils, scriptural meditation, nakedness and total deprivation do not constitute perfection but are the means to perfection. They are not in themselves the end point of a discipline, but an end is attained to through them.
To act 'according to one’s strength' means to use a little less than necessary both of food, and drink, and sleep... As for food, restrain yourself when you wish to eat a little more, and in this way you will always make use of it moderately.
The enemy is within ourselves. An invisible war is taking place within us. If interior evil is defeated, then the external, weaker, foe will surrender.
How great the evil of pride is, that it deserves to have as its adversary not an angel or other virtues contrary to it but rather God Himself! For it must be noted that it is never said of those who are caught up in the other vices that the Lord resists them, or that the Lord is set against the gluttonous, or fornicators, or the angry, or the avaricious; this is true of the proud alone. For those vices only turn back upon wrongdoers or seem to be committed against those who have a part in them -- that is, against other human beings. This one, however, of its very nature touches God, and therefore it is specially worthy of having God opposed to it.
