If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
Angels are a light for monks, and the monastic life is a light for all men. Therefore let monks strive to become a good example in everything, giving no occasion for stumbling in anything (II Corinthians 6:3) in all their works and words. For if the light becomes darkness, how much darker will be that darkness, that is, those living in the world.
Keep your mind from malicious thoughts of your neighbors, knowing that such thoughts are hurled by diabolical power, to keep your mind from your own sins and from seeking.
Those who mourn and those who are insensitive are not subject to fear, but the cowardly often have become deranged. And this is natural. For the Lord rightly forsakes the proud that the rest of us may learn not to be puffed up.
The flow of history confirms the reality of the Gospel: the Church is filled to overflowing with sinners. Does their presence in the Church reduce, violate, or destroy her sanctity? Not in the least! For her Head—the Lord Christ, and her Soul—the Holy Spirit, and her divine teaching, her mysteries, and her virtues, are indissolubly and immutably holy. The Church tolerates sinners, shelters them, and instructs them, that they may be awakened and roused to repentance and spiritual recovery and transfiguration; but they do not hinder the Church from being holy. Only unrepentant sinners, persistent in evil and godless malice, are cut off from the Church either by the visible action of the theanthropic authority of the Church or by the invisible action of divine judgment, so that thus also the holiness of the Church may be preserved.
Stint your stomach and you will certainly lock your mouth, because the tongue is strengthened by an abundance of food. Struggle with all your might against the stomach and restrain it with all sobriety. If you labor a little, the Lord will also soon work with you.
Silence of lips is better and more wonderful than any edifying conversation. Strive to acquire humility and submissiveness. Never insist that anything should be according to your will, for this gives birth to anger. Do not judge or humiliate anyone, for this gives birth to anger. Do not judge or humiliate anyone, for this exhausts the heart and blinds the mind, and thereon leads to negligence and makes the heart unfeeling.
The fathers have laid down that psalmody is a weapon, and prayer is a wall, and honest tears are a bath; but blessed obedience in their judgment is confession of faith, without which no one subject to the passions will see the Lord.
