Ecclesiastes 4:10

"And he began to send them forth two by two." He sent them two by two that no one of them, being abandoned and alone, might fall into a denial, like Peter, or flee, like John. Human frailty quickly falls if it proudly relies on …

Therefore, since most embrace virginity while still young and unformed in understanding, this before anything else should be their employment, to search out a fitting guide and master of this way, lest, in their present ignorance, they should wander from the direct route, and strike out new paths of their own in trackless wilds. "Two are better than one," says the Preacher; but a single one is easily vanquished by the foe who infests the path which leads to God; and verily "woe to him that is alone when he falleth, for he hath not another to help him up." Some ere now in their enthusiasm for the stricter life have shown a dexterous alacrity; but, as if in the very moment of their choice they had already touched perfection, their pride has had a shocking fall, and they have been tripped up from madly deluding themselves into thinking that that to which their own mind inclined them was the true beauty. In this number are those whom Wisdom calls the "slothful ones," who bestrew their "way" with "thorns"; who think it a moral loss to be anxious about keeping the commandments; who erase from their own minds the Apostolic teaching, and instead of eating the bread of their own honest earning fix on that of others, and make their idleness itself into an art of living. From this number, too, come the Dreamers, who put more faith in the illusions of their dreams than in the Gospel teaching, and style their own phantasies "revelations." Hence, too, those who "creep into the houses"; and again others who suppose virtue to consist in savage bearishness, and have never known the fruits of long-suffering and humility of spirit.

"Two are better than one, for they get a greater return for their labour. For should they fall, one can raise the other; but woe to him who is alone when he falls and there is no one to raise him! Also, if two sleep together they keep warm, but how can one be warm alone? Where one can be overpowered, two can resist attack; A three-ply cord is not easily severed!"

In the solitary life, what is at hand becomes useless to us and what is wanting cannot be provided, since God the Creator decreed that we should require the help of one another, as it is written, so that we might associate with one another. Again, apart from this consideration, the doctrine of the charity of Christ does not permit the individual to be concerned solely with his own private interests. "Charity," says the apostle, "seeks not her own." But a life passed in solitude is concerned only with the private service of individual needs. This is openly opposed to the law of love, which the apostle fulfilled, who sought not what was profitable to himself but to many that they might be saved. Furthermore, a person living in solitary retirement will not readily discern his own defects, since he has no one to admonish and correct him with mildness and compassion. In fact, admonition even from an enemy often produces in a prudent person the desire for amendment. But the cure of sin is wrought with understanding by him who loves sincerely. Holy Scripture says, "for he that loves, at times corrects." Such a one it is very difficult to find in solitude, if in one's prior state of life one had not been associated with such a person. The solitary, consequently, experiences the truth of the saying, "Woe to him that is alone, for when he falls he has none to lift him up." Moreover, the majority of the commandments are easily observed by several persons living together, but not so in the case of one living alone, for while he is obeying one commandment, the practice of another is being interfered with. For example, when he is visiting the sick, he cannot show hospitality to the stranger, and in the imparting and sharing of necessities (especially when the ministrations are prolonged), he is prevented from giving zealous attention to [other] tasks.

On account of raising up he says: "If one falls, he will be supported by the other": Deuteronomy 22: "If you see the donkey of your brother fallen on the road, you shall not despise it, but shall lift it up with him." The solitary …
