18. But in good truth it is a serious demand to make upon us, to continue discoursing on to the set limit when we fail to see our hearer in any degree moved; whether it be that, under the restraints of the awe of religion, he has not the boldness to signify his approval by voice or by any movement of his body, or that he is kept back by the modesty proper to man, or that he does not understand our sayings, or that he counts them of no value. Since, then, this must be a matter of uncertainty to us, as we cannot discern his mind, it becomes our duty in our discourse to make trial of all things which may be of any avail in stirring him up and drawing him forth as it were from his place of concealment. For that sort of fear which is excessive, and which obstructs the declaration of his judgment, ought to be dispelled by the force of kindly exhortation; and by bringing before him the consideration of our brotherly affinity, we should temper his reverence for us; and by questioning him, we should ascertain whether he understands what is addressed to him; and we should impart to him a sense of confidence, so that he may give free expression to any objection which suggests itself to him. We should at the same time ask him whether he has already listened to such themes on some previous occasion, and whether perchance they fail to move him now in consequence of their being to him like things well known and commonplace. And we ought to shape our course in accordance with his answer, so as either to speak in a simpler style and with greater detail of explanation, or to refute some antagonistic opinion, or, instead of attempting any more diffuse exposition of the subjects which are known to him, to give a brief summary of these, and to select some of those matters which are handled in a mystical manner in the holy books, and especially in the historical narrative, the unfolding and setting forth of which may make our addresses more attractive. But if the man is of a very sluggish disposition, and if he is senseless, and without anything in common with all such sources of pleasure, then we must simply bear with him in a compassionate spirit; and, after briefly going over other points, we ought to impress upon him, in a manner calculated to inspire him with awe, the truths which are most indispensable on the subject of the unity of the Catholic Church, on that of temptation, on that of a Christian conversation in view of the future judgment; and we ought rather to address ourselves to God for him than address much to him concerning God.
