Translated by Alexander Roberts and James Donaldson.
The Instructor being practical, not theoretical, His aim is thus to improve the soul, not to teach, and to train it up to a virtuous, not to an intellectual life. Although this same word is didactic, but not in the present instance. For the word which, in matters of doctrine, explains and reveals, is that whose province it is to teach. But our Educator  being practical, first exhorts to the attainment of right dispositions and character, and then persuades us to the energetic practice of our duties, enjoining on us pure commandments, and exhibiting to such as come after representations of those who formerly wandered in error. Both are of the highest utility,--that which assumes the form of counselling to obedience, and that which is presented in the form of example; which latter is of two kinds, corresponding to the former duality,--the one having for its purpose that we should choose and imitate the good, and the other that we should reject and turn away from the opposite.
Hence accordingly ensues the healing of our passions, in consequence of the assuagements of those examples; the Paedagogue strengthening our souls, and by His benign commands, as by gentle medicines, guiding the sick to the perfect knowledge of the truth.
There is a wide difference between health and knowledge; for the latter is produced by learning, the former by healing. One, who is ill, will not therefore learn any branch of instruction till he is quite well. For neither to learners nor to the sick is each injunction invariably expressed similarly; but to the former in such a way as to lead to knowledge, and to the latter to health. As, then, for those of us who are diseased in body a physician is required, so also those who are diseased in soul require a paedagogue to cure our maladies; and then a teacher, to train and guide the soul to all requisite knowledge when it is made able to admit the revelation of the Word. Eagerly desiring, then, to perfect us by a gradation conducive to salvation, suited for efficacious discipline, a beautiful arrangement is observed by the all-benignant Word, who first exhorts, then trains, and finally teaches.
 The paedagogus. [This word seems to be used by Clement, with frequent alusion, at least, to its original idea, of one who leads the child to his instructor; which is the true idea, I suppose, in Gal. iii. 24.]
