Chapter III. How friendship is indissoluble. Among all these then there is one kind of love which is indissoluble, where the union is owing not to the favour of a recommendation, or some great kindness or gifts, or the reason of some bargain, or the necessities of nature, but simply to similarity of virtue. This, I say, is what is broken by no chances, what no interval of time or space can sever or destroy, and what even death itself cannot part. This is true and unbroken love which grows by means of the double perfection and goodness of friends, and which, when once its bonds have been entered, no difference of liking and no disturbing opposition of wishes can sever. But we have known many set on this purpose, who though they had been joined together in companionship out of their burning love for Christ, yet could not maintain it continually and unbrokenly, because although they relied on a good beginning for their friendship, yet they did not with one and the same zeal maintain the purpose on which they had entered, and so there was between them a sort of love only for a while, for it was not maintained by the goodness of both alike, but by the patience of the one party, and so although it is held to by the one with unwearied heroism, yet it is sure to be broken by the pettiness of the other. For the infirmities of those who are somewhat cold in seeking the healthy condition of perfection, however patiently they may be borne by the strong, are yet not put up with by those who are weaker themselves. For they have implanted within them causes of disturbance which do not allow them to be at ease, just as those, who are affected by bodily weakness, generally impute the delicacy of their stomach and weak health to the carelessness of their cooks and servants, and however carefully their attendants may serve them, yet nevertheless they ascribe the grounds of their upset to those who are in good health, as they do not see that they are really due to the failure of their own health. Wherefore this, as we said, is the sure and indissoluble union of friendship, where the tie consists only in likeness in goodness. For “the Lord maketh men to be of one mind in an house.” 1966 And therefore love can only continue undisturbed in those in whom there is but one purpose and mind to will and to refuse the same things. And if you also wish to keep this unbroken, you must be careful that having first got rid of your faults, you mortify your own desires, and with united zeal and purpose diligently fulfil that in which the prophet specially delights: “Behold how good and joyful a thing it is for brethren to dwell together in unity.” 1967 Which should be taken of unity of spirit rather than of place. For it is of no use for those who differ in character and purpose to be united in one dwelling, nor is it an hindrance for those who are grounded on equal goodness to be separated by distance of place. For with God the union of character, not of place, joins brethren together in a common dwelling, nor can unruffled peace ever be maintained where difference of will appears. 1966     Ps. lxvii.
