The answer, that leave to lie, which was not even granted under the old Covenant, has rightly been taken by many.
Joseph: All liberty in the matter of wives and many concubines, as the end of time is approaching and the multiplying of the human race completed, ought rightly to be cut off by evangelical perfection, as being no longer necessary. For up to the coming of Christ it was well that the blessing of the original sentence should be in full vigour, whereby it was said: “Increase and multiply, and fill the earth.” 2025 And therefore it was quite right that from the root of human fecundity which happily flourished in the synagogue, in accordance with that dispensation of the times, the buds of angelical virginity should spring, and the fragrant flowers of continence be produced in the Church. But that lying was even then condemned the text of the whole Old Testament clearly shows, as it says: “Thou shalt destroy all them that speak lies;” and again: “The bread of lying is sweet to a man, but afterwards his mouth is filled with gravel;” and the Giver of the law himself says: “Thou shalt avoid a lie.” 2026 But we said that it was then properly employed as a last resort when some need or plan of salvation was linked on to it, on account of which it ought not to be condemned. As is the case, which you mentioned, of king David when in his flight from the unjust persecution of Saul, to Abimelech the priest he used lying words, not with the object of getting any gain nor with the desire to injure anybody, but simply to save himself from that most iniquitous persecution; inasmuch as he would not stain his hands with the blood of the hostile king, so often delivered up to him by God; as he said: “The Lord be merciful to me that I may do no such thing to my master the Lords anointed, as to lay my hand upon him, because he is the Lords anointed.” 2027 And therefore these plans which we hear that holy men under the old covenant adopted either from the will of God, or for the prefiguring of spiritual mysteries or for the salvation of some people, we too cannot refuse altogether, when necessity constrains us, as we see that even apostles did not avoid them, where the consideration of something profitable required them: which in the meanwhile we will for a time postpone, while we first discuss those instances which we propose still to bring forward from the Old Testament, and afterwards we shall more suitably introduce them so as more readily to prove that good and holy men, both in the Old and in the New Testament, were entirely at one with each other in these contrivances. For what shall we say of that pious fraud of Hushai to Absalom for the salvation of king David, which though uttered with all appearance of good-will by the deceiver and cheat, and opposed to the good of him who asked advice, is yet commended by the authority of Holy Scripture, which says: “But by the will of the Lord the profitable counsel of Ahithophel was defeated that the Lord might bring evil upon Absalom?” 2028 Nor could that be blamed which was done for the right side with a right purpose and pious intent, and was planned for the salvation and victory of one whose piety was pleasing to God, by a holy dissimulation. What too shall we say of the deed of that woman, who received the men who had been sent to king David by the aforesaid Hushai, and hid them in a well, and spread a cloth over its mouth, and pretended that she was drying pearl-barley, and said “They passed on after tasting a little water”; 2029 and by this invention saved them from the hands of their pursuers? Wherefore answer me, I pray you, and say what you would have done, if any similar situation had arisen for you, living now under the gospel; would you prefer to hide them with a similar falsehood, saying in the same way: “They passed on after tasting a little water,” and thus fulfil the command: “Deliver those who are being led to death, and spare not to redeem those who are being killed;” 2030 or by speaking the truth, would you have given up those in hiding to the men who would kill them? And what then becomes of the Apostles words: “Let no man seek his own but the things of another:” and: “Love seeketh not her own, but the things of others;” and of himself he says: “I seek not mine own good but the good of many that they may be saved?” 2031 For if we seek our own, p. 467 and want obstinately to keep what is good for ourselves, we must even in urgent cases of this sort speak the truth, and so become guilty of the death of another: but if we prefer what is for anothers advantage to our own good, and satisfy the demands of the Apostle, we shall certainly have to put up with the necessity of lying. And therefore we shall not be able to keep a perfect heart of love, or to seek, as Apostolic perfection requires, the things of others, unless we relax a little in those things which concern the strictness and perfection of our own lives, and choose to condescend with ready affection to what is useful to others, and so with the Apostle become weak to the weak, that we may be able to gain the weak.
