“Speak every man truth with his neighbour,”[251] was from early times regarded as one of the most imperative of Christian maxims.[252] According to St. Augustine, a lie is not permissible even when told with a view to saving the life of a neighbour; “since by lying eternal life is lost, never for any man’s temporal life must a lie be told.”[253] Yet all lies are not equally sinful; the degree of sinfulness depends on the mind of the liar and on the nature of the subject on which the lie is told.[254] This became the authorised doctrine of the Church.[255] Thomas Aquinas says that, although lying is always sinful, it is not a mortal sin if the end intended be not contrary to charity, “as appears in a jocose lie, that is intended to create some slight amusement, and in an officious lie, in which is intended even the advantage of our neighbour.”[256] Yet from early times we meet within the Christian Church a much less rigorous doctrine, which soon came to exercise a more powerful influence on the practice and feelings of men than did St. Augustine’s uncompromising love of truth. The Greek Fathers maintained that an untruth is not a lie when there is a “just cause” for it; and as a just cause they regarded not only self-defence, but also zeal for God’s honour.[257] This zeal, together with an indiscriminate devotion to the Church, led to those “pious frauds,” those innumerable falsifications of documents, inventions of legends, and forgeries of every description, which made the Catholic Church a veritable seat of lying, and most seriously impaired the sense of truth in the minds of Christians.[258] By a fiction, Papacy, as a divine institution, was traced back to the age of the Apostles, and in virtue of another fiction Constantine was alleged to have abdicated his imperial authority in Italy in favour of the successor of St. Peter.[259] The Bishop of Rome assumed the privilege of disengaging men from their oaths and promises. An oath which was contrary to the good of the Church was declared not to be binding.[260] The theory was laid down that, as faith was not to be kept with a tyrant, pirate, or robber, who kills the body, it was still less to be kept with an heretic, who kills the soul.[261] Private protestations were thought sufficient to relieve men in conscience from being bound by a solemn treaty or from the duty of speaking the truth; and an equivocation, or play upon words in which one sense is taken by the speaker and another sense intended by him for the hearer, was in some cases held permissible.[262] According to Alfonso de’ Liguori—who lived in the eighteenth century and was beatified in the nineteenth, and whose writings were declared by high authority not to contain a word that could be justly found fault with,[263]—there are three sorts of equivocation which may be employed for a good reason, even with the addition of a solemn oath. We are allowed to use ambiguously words having two senses, as the word volo, which means both to “wish” and to “fly”; sentences bearing two main meanings, as “This book is Peter’s,” which may mean either that the book belongs to Peter or that Peter is the author of it; words having two senses, one more common than the other or one literal and the other metaphorical—for instance, if a man is asked about something which it is in his interest to conceal, he may answer, “No, I say,” that is “I say the word ‘no’”[264] As for mental restrictions, again, such as are “purely mental,” and on that account cannot in any manner be discovered by other persons, are not permissible; but we may, for a good reason, make use of a “non-pure mental restriction,” which, in the nature of things, is discoverable, although it is not discovered by the person with whom we are dealing.[265] Thus it would be wrong secretly to insert the word “no” in an affirmative oath without any external sign; but it would not be wrong to insert it in a whispering voice or under the cover of a cough. The “good reason” for which equivocations and non-pure mental restrictions may be employed is defined as “any honest object, such as keeping our goods spiritual or temporal.”[266] In support of this casuistry it is uniformly said by Catholic apologists that each man has a right to act upon the defensive, that he has a right to keep guard over the knowledge which he possesses in the same way as he may defend his goods; and as for there being any deceit in the matter—why, soldiers use stratagems in war, and opponents use feints in fencing.[267]
