From the days of Chrysostom and Augustine to the present time, all discussions of this question have been but a repetition of the arguments and objections then brought forward and examined. There can be, in fact, only two positions maintained with any show of logical consistency. Either a lie is in its very nature antagonistic to the being of God, and therefore not to be used or approved by him, whatever immediate advantages might accrue from it, or whatever consequences might pivot on its rejection; or a lie is not in itself a sin, is not essentially at variance with the nature of God, but is good or evil according to the spirit of its use, and the end to be gained by it; and therefore on occasions God could lie, or could approve lying on the part of those who represent him. The first of these positions is that maintained by the Shepherd of Hermas, by Justin Martyr, by Basil the Great, and by Augustine; the second is practically that occupied by Gregory of Nyssa and Chrysostom, even though they do not explicitly define, or even seem to perceive, it as their position. There are, again, those like Origen and Jerome, who are now on one side of the dividing line, and now on the other; but they are not logically consistent with themselves in their opinions or practices. And those who are not consistent usually refrain from explicit definitions of the lie and of falsehood; they make no attempt at distinguishing between justifiable concealment, and concealment for the very purpose of deception. With all the arguments on this question, in all the centuries, comprised within these well-defined bounds, it were useless to name each prominent disputant, in order merely to classify him as on the one side or on the other, or as zigzagging along the line which he fails to perceive. It were sufficient to point out a few pre-eminent mountain peaks, in the centuries between the fifth and the nineteen of the Christian era, as indicative of the perspective history of this discussion. Towering above the greatest of the Schoolmen in the later middle ages stands Thomas Aquinas. As a man of massive intellect, of keenness of perception, of consistent logical instincts, and of unquestioned sincerity and great personal devoutness, we might expect him to be found, like Augustine, on the side of principle against policy, in unqualified condemnation of lying under any circumstances whatsoever, and in advocacy of truthfulness at all hazards. And that, as a matter of fact, is his position.
