This is the mark of Christianity--however much a man toils, and however many righteousnesses he performs, to feel that he has done nothing, and in fasting to say, 'This is not fasting,' and in praying, 'This is not prayer,' and in perseverance at prayer, 'I have shown no perseverance; I am only just beginning to practice and to take pains;' and even if he is righteous before God, he should say, 'I am not righteous, not I; I do not take pains, but only make a beginning every day.'
Many teach their children about worldly politics, others teach them to speak foreign languages: French, German, Italian, and in this spend no trifling sums. Others endeavor to teach them commerce and other arts. But hardly anyone teaches them to live in a Christian manner. However, without this, all learning is nothing and all wisdom is madness. For what does it profit a Christian to speak Italian, French and German, if he lives in an ungodly manner? What use is it to be skilled in commerce and the arts if one lacks the fear of God? God will not ask you whether you taught your children French, German or Italian or the politics of social life--but you will not escape divine reprobation for not having instilled goodness into them. I speak plainly but I tell the truth: if your children are bad, your grandchildren will be worse, and the evil will thus increase...and the root of all this is our thoroughly bad education.
The husband and wife must lay virtue, and not passion, as the foundation of their love, that is, when the husband sees any fault in his wife, he must nudge her meekly, and the wife must submit to her husband in this. Likewise when a wife sees some fault in her husband, she must exhort him, and he is obliged to hear her. In this manner their love will be faithful and unbroken, and thereby having mutually composed their happiness, they shall take pleasure in the virtue.
No Christian believing rightly in God should ever be off his guard. He should always be on the look-out for temptation, so that when it comes he will not be surprised or disturbed, but will gladly endure the toil and affliction it causes, and so will understand what he is saying when he chants with the prophet: 'Prove me, O Lord, and try me' (Ps. 26:2 LXX). For the prophet did not say, 'Thy correction has destroyed me,' but, 'it has upheld me to the end' (Ps. 18:35 LXX).
A haughty person is not aware of his faults, or a humble person of his good qualities. An evil ignorance blinds the first, an ignorance pleasing to God blinds the second.
Christians should judge no one, neither an open harlot, nor sinners, nor dissolute people, but should look upon all with simplicity of soul and a pure eye. Purity of heart, indeed, consists in seeing sinful and weak men and having compassion for them and being merciful.
When a man gives God his secret things, that is, his mind and thoughts, not occupying himself elsewhere, nor wandering away, but putting constraint upon himself, then the Lord deems him worthy of mysteries, in greater sanctity and purity, and gives him heavenly food and spiritual drink
For love does not seek its own, it labors, sweats, watches to build up the brother: nothing is inconvenient to love, and by the help of God it turns the impossible into the possible.... Love believes and hopes.... It is ashamed of nothing. Without it, what is the use of prayer? What use are hymns and singing? What is the use of building and adorning churches? What is mortification of the flesh if the neighbor is not loved? Indeed, all are of no consequence. As an animal cannot exist without bodily warmth, so no good deed can be alive without true love; it is only the pretence of a good deed.
