Chapter III. Love of Enemies
Nor even enemies and those who injure us are excluded from the law of charity; in spite of their ill will and malice they remain our neighbours, and our Lord expressly bade us love them: “I say to you: Love your enemies; do good to them that hate you, and pray for them that persecute and calumniate you.”1 We are bound by this precept to put out of our hearts all ill feeling and desire of revenge against those who dislike and wrong us, and furthermore we are bound to show them those common marks of Christian charity which are due to all and may be refused to none. What those common marks of Christian charity are depends much on the usages of time and place, and of the society to which the parties belong. Those marks which are common to members of the same family are not due to outsiders; those which are mutually shown to neighbours of the same social standing are not due to utter strangers or to persons in a lower social position. Among the common signs of charity which may be refused to none are reckoned the following: general prayer for all which we offer up when we say the Our Father, answering a question or returning a salute, selling in open market to all comers, refraining from excluding individuals from general invitations or general benefactions, It is not of precept but of counsel to show one’s enemies unusual signs of forgiveness and charity. Such signs are to pray expressly for an enemy in particular, to visit him, to console him in affliction, to treat familiarly with him.
1 Matt. v 44.
p. i, 120
In certain circumstances, however, we are bound to show even these unusual signs of charity to our enemy, as when they cannot be refused without scandal to others who will think that they are refused through hatred, or when they are required to prevent our enemy from falling into serious sin as, for example, by conceiving a deeper hatred for us. If a former friend asks our pardon for an injury which he has done us, and if the friendship was not a freely accepted union between us, but was more or less required by our mutual relations, we must be ready to show him again unusual signs of charity. If the friendship depended merely on our mutual liking, there will be no obligation to show unusual marks of charity after receiving an offence; what was freely given may be freely withheld, always supposing that there is no ill will. We may for a time even refuse the common and ordinary signs of charity toward another for a good reason. A superior, for example, may do so in order to correct an inferior who has offended him. An equal may do so for a time immediately after receiving an offence while the injury is still rankling in his heart; to require not only repression of ill feeling, but the immediate exhibition of marks of charity for the offender, would be to lay too heavy a burden on poor human nature. It may also be lawful to refuse the ordinary signs of charity for a time toward one who has offended us in lighter matters as a suitable punishment, and as a means of preventing a repetition of such offences in future.
p. i, 120
When one who has offended us apologizes and asks for pardon we are bound to forgive him and also at the proper time to show him the ordinary signs of charity. If, however, he has injured us, we have a right to compensation for the injustice, and charity does not compel us to forego our right. We may then require satisfaction for the injury and even bring an action in a court of law to recover it against the wrongdoer, without, of course, indulging any ill will.
p. i, 121
With a view to reconciliation between enemies, it is the duty of him who gave the offence to apologize and to ask for pardon, unless a position of superiority makes this inadvisable. As a rule, it will not be necessary to make a formal request for pardon; satisfaction can usually be given to the offended party in a less formal way, and in a way that is less embarrassing to both parties. If both were in the wrong, the one who was most so, or the inferior, should be the first to seek reconciliation.
p. i, 121
We sometimes find it difficult to associate with certain people; they try our temper; we can scarcely talk or think of them with patience. This is sinful, of course, if it is voluntary, and if it arises from ill will towards the person in question. It sometimes, however, comes not from ill will towards the person, but from incompatibility of characters and dispositions. We dislike in him some quality or mannerism, or something which we cannot precisely define. It is what theologians call the hatred of abomination, not of enmity, and it may be without fault, as when it leads us to fly his company not in order to wound his feelings, but to escape a trial of temper and probable unpleasantness.
To refuse the ordinary signs of charity so as not to speak to another, or to refuse to have anything to do with him out of ill feeling, and to foster this for a considerable time, is of itself a grave sin. But in estimating the gravity of such a sin in practice, the cause and the strength of the ill feeling should be considered. If the refusal to have anything to do with another come from serious ill will, it will be a grievous sin; otherwise it may be only venial, or if there be no ill will and a just cause, no sin at all,
