He who addresses those who are present before him, both tests them by time, and judges by his judgment, and from the others distinguishes him who can hear; watching the words, the manners, the habits, the life, the motions, the attitudes, the look, the voice; the road, the rock, the beaten path, the fruitful land, the wooded region, the fertile and fair and cultivated spot, that is able to multiply the seed. But he that speaks through books, consecrates himself before God, crying in writing thus: Not for gain, not for vainglory, not to be vanquished by partiality, nor enslaved by fear, nor elated by pleasure; but only to reap the salvation of those who read, which he does not at present participate in, but awaiting in expectation the recompense which will certainly be rendered by Him, who has promised to bestow on the labourers the reward that is meet. But he who is enrolled in the number of men[822] ought not to desire recompense. For he that vaunts his good services, receives glory as his reward. And he who does any duty for the sake of recompense, is he not held fast in the custom of the world, either as one who has done well, hastening to receive a reward, or as an evildoer avoiding retribution? We must, as far as we can, imitate the Lord. And he will do so, who complies with the will of God, receiving freely, giving freely, and receiving as a worthy reward the citizenship itself. “The hire of an harlot shall not come into the sanctuary,” it is said: accordingly it was forbidden to bring to the altar the price of a dog. And in whomsoever the eye of the soul has been blinded by ill-nurture and teaching, let him advance to the true light, to the truth, which shows by writing the things that are unwritten. “Ye that thirst, go to the waters,”[823] says Esaias. And “drink water from thine own vessels,”[824] Solomon exhorts. Accordingly in “The Laws,” the philosopher who learned from the Hebrews, Plato, commands husbandmen not to irrigate or take water from others, until they have first dug down in their own ground to what is called the virgin soil, and found it dry. For it is right to supply want, but it is not well to support laziness. For Pythagoras said that, “although it be agreeable to reason to take a share of a burden, it is not a duty to take it away.” Now the Scripture kindles the living spark of the soul, and directs the eye suitably for contemplation; perchance inserting something, as the husbandman when he ingrafts, but, according to the opinion of the divine apostle, exciting what is in the soul. “For there are certainly among us many weak and sickly, and many sleep. But if we judge ourselves, we shall not be judged.”[825] Now this work of mine in writing is not artfully constructed for display; but my memoranda are stored up against old age, as a remedy against forgetfulness, truly an image and outline of those vigorous and animated discourses which I was privileged to hear, and of blessed and truly remarkable men.
