On the Good of Marriage

²⁸ Therefore, if we compare the things themselves, we may no way doubt that the chastity of continence is better than marriage chastity, while yet both are good: but when we compare the persons, he is better, who has a greater good than another. Further, he who has a greater of the same kind, has also that which is less; but he, who only has what is less, assuredly has not that which is greater. For in sixty, thirty also are contained, not sixty also in thirty. But not to work from out that which he has, stands in the allotment of duties, not in the want of virtues: forasmuch as neither is he without the good of mercy, who finds not wretched persons such as he may mercifully assist.
