1 Cor. iii.16, 17 c39. And all these sins, truly, whether such whereby an injury is done to men in the comforts of this life, or whereby men corrupt themselves and hurt none against his will: all these sins, then, even though they seem to mean well by this temporal life to the procuring of any delight or profit, (for no man commits any of these things with any other purpose and end;) yet in regard of that life which is forever and ever, they do entangle and in all ways hinder. But there are some of these that hinder the doers only, others likewise those on whom they are done. For as to the things which people keep safe for the sake of utility to this life, when these are taken away by injurious persons, they alone sin and are hindered from eternal life who do this, not they to whom they do it. Therefore, even if a person consent to the taking of them from him, either that he may not do some evil, or that he may not in these very things suffer some greater inconvenience; not only does he not sin, but in the one case he acts bravely and laudably, in the other usefully and unblameably. But as to those things which are kept for the sake of sanctity and religion, when injurious persons wish to violate these, it is right, if the condition be proposed and the means given, to redeem them even by sins of lesser moment, yet not by wrongs to other men. And then do these things thenceforth cease to be sins, which are undertaken in order to the avoidance of greater sins. For as in things useful, for instance in pecuniary or any other corporal commodity, that is not called a loss which is parted with in order to a greater gain; so in things holy, that is not called sin which is admitted lest a worse be admitted. Or if that is called loss, which one foregoes that he may not forego more; let this also be called sin, while however the necessity of undertaking it in order to the eschewing of a greater is no more to be doubted, than that, in order to avoid a greater loss, it is right to suffer a smaller one. c40. Now the things which are to be kept safe for sanctity's sake are these: pudicity of body, and chastity of soul,  and verity of doctrine. Pudicity of body, without consent and permission of the soul, doth no man violate. For, whatever against our will and without our empowering the same is by greater force done upon our body, is no lewdness. Howbeit, of permitting there may be some reason, but of consenting, none. For we consent, when we approve and wish: but we permit even not willing, because of some greater turpitude to be eschewed. Consent, truly, to corporal lewdness violates also chastity of mind. For the mind's  chastity consists in a good will and sincere love, which is not corrupted, unless when we love and desire that which Truth teaches ought not to be loved and desired. We have therefore to guard the sincerity of love toward God and our neighbor; for in this is chastity of mind sanctified: and we must endeavor with all the strength in our power, and with pious supplication, that, when the pudicity of our body is sought to be violated, not even that outermost sense of the soul,  which is entangled with the flesh, may be touched with any delight; but if it cannot this, at least the mind and thought  in not consenting may have its chastity preserved entire. Now what we have to guard in chastity of mind,  is, as pertaining to the love of our neighbor, innocence and benevolence; as pertaining to the love of God, piety. Innocence is that we hurt no man; benevolence, that we also do good to whom we can; piety, that we worship God. But as for verity of doctrine, of religion and piety, that is not violated unless by a lie; whereas the highest and inmost Verity Itself, Whose that doctrine is, can in no wise be violated: which Truth to attain unto, and in It on every wise to remain, and to It thoroughly to cleave, will not be permitted, but when this corruptible shall have put on incorruption, and this mortal shall have put on immortality. But, because all piety in this life is practice by which we tend to that life, which practice hath a guidance afforded unto it from that doctrine, which in human words and signs  of corporal sacraments doth insinuate and intimate Truth herself: for this cause this also, which by lying is possible to be corrupted, is most of all to be kept incorrupt; that so, if aught in that chastity of mind be violated, it may have that wherefrom it may be repaired. For once corrupt authority of doctrine, and there can be none either course or recourse to chastity of mind.
