"If your brother sin against you in word, and make amends to you, receive him seven times in a day." Simon, His disciple, said to Him, "Seven times in a day?" The Lord answered and said to him, "I say unto you until seventy times seven."
Moreover, debt is, in the Scriptures, a figure of guilt; because it is equally due to the sentence of judgment, and is exacted by it: nor does it evade the justice of exaction, unless the exaction be remitted, just as the lord remitted to that slave in the parable his debt; for hither does the scope of the whole parable tend.
And when Peter had put the question whether remission were to be granted to a brother seven times, "Nay," saith He, "seventy-seven times; " in order to remould the Law for the better; because in Genesis vengeance was assigned "seven times" in the case of Cain, but in that of Lamech "seventy-seven times.
As regards the rule of peace, which is so pleasing to God, who in the world that is prone to impatience will even once forgive his brother, I will not say "seven times," or "seventy-seven times? " Who that is contemplating a suit against his adversary will compose the matter by agreement, unless he first begin by lopping off chagrin, hardheartedness, and bitterness, which are in fact the poisonous outgrowths of impatience? How will you "remit, and remission shall be granted" you if the absence of patience makes you tenacious of a wrong? No one who is at variance with his brother in his mind, will finish offering his "duteous gift at the altar," unless he first, with intent to "re-conciliate his brother," return to patience.
Or, In whatever the two testaments are in agreement, for this every prayer is found acceptable to God.
Or, because the number six seems to denote toil and labour, and the number seven repose, He says that forgiveness should be given to all brethren who live in this world, and sin in the things of this world. But if any commit transgressions beyond these things, he shall then have no further forgiveness.
When Peter asked him whether he should forgive his brother sinning against him up to seven times, the Lord replied, “Not up to seven times but up to seventy times seven times.” In every way he teaches us to be like him in humility and goodness. In weakening and breaking the impulses of our rampant passions he strengthens us by the example of his leniency, by granting us in faith pardon of all our sins. For the vices of our nature did not merit pardon. Therefore all pardon comes from him. In fact, he pardons even those sins that remain in one after confession.The penalty to be paid through Cain was established at sevenfold, but that sin was against a man, against his brother Abel, to the point of murder. But in Lamech the penalty was established at seventy times seven times, and, as we believe, the penalty was established on those responsible for the Lord’s Passion. But the Lord through the confession of believers grants pardon for this crime. By the gift of baptism he grants the grace of salvation to his revilers and persecutors. How much more is it necessary, he shows, that pardon be returned by us without measure or number. And we should not think how many times we forgive, but we should cease to be angry with those who sin against us, as often as the occasion for anger exists. Pardon’s frequency shows us that in our case there is never a time for anger, since God pardons us for all sins in their entirety by his gift rather than by our merit. Nor should we be excused from the requirement of giving pardon that number of times [i.e., seventy times seven], since through the grace of the gospel God has granted us pardon without measure.
(Hom. lxi.) Peter thought that he had made a large allowance; but what answers Christ the Lover of men? it follows, Jesus saith unto him, I say not unto thee, Until seven times, but, Until seventy times seven.
When He says, Until seventy times seven, He does not limit a definite number within which forgiveness must be kept; but He signifies thereby something endless and ever enduring.
Peter supposed he was saying something great, wherefore also as aiming at greatness he added, "Until seven times?" For this thing, saith he, which Thou hast commanded to do, how often shall I do? For if he forever sins, but forever when reproved repents, how often dost thou command us to bear with this man? For with regard to that other who repents not, neither acknowledges his own faults, Thou hast set a limit, by saying, "Let him be to thee as the heathen and the publican;" but to this no longer so, but Thou hast commanded to accept him.
How often then ought I to bear with him, being told his faults, and repenting? Is it enough for seven times?
What then saith Christ, the good God, who is loving towards man? "I say not unto thee, until seven times, but, until seventy times seven," not setting a number here, but what is infinite and perpetual and forever. For even as ten thousand times signifies often, so here too. For by saying, "The barren hath borne seven," the Scripture means many. So that He hath not limited the forgiveness by a number, but hath declared that it is to be perpetual and forever.
This at least He indicated by the parable that is put after. For that He might not seem to any to enjoin great things and hard to bear, by saying, "Seventy times seven," He added this parable, at once both leading them on to what He had said, and putting down him who was priding himself upon this, and showing the act was not grievous, but rather very easy. Therefore let me add, He brought forward His own love to man, that by the comparison, as He saith, thou mightest learn, that though thou forgive seventy times seven, though thou continually pardon thy neighbor for absolutely all his sins, as a drop of water to an endless sea, so much, or rather much more, doth thy love to man come short in comparison of the boundless goodness of God, of which thou standest in need, for that thou art to be judged, and to give an account.
The Lord had said above, See that ye despise not one of these little ones, and had added, If thy brother sin against thee, &c. making also a promise, If two of you, & c. by which the Apostle Peter was led to ask, Lord, how oft shall my brother sin against me, and I forgive him? And to his question he adds an opinion, Until seven times?
Or understand it of four hundred and ninety times, that He bids us forgive our brother so oft.
(Verse 21, 22.) Then Peter came to him and said, Lord, how often shall my brother sin against me, and I forgive him? Up to seven times? Jesus said to him, I do not say to you, up to seven times, but up to seventy times seven. The Lord's words weighed heavily on him, and they could not be broken like a triple cord. Earlier, he had said, See that you do not despise one of these little ones; and he had added, If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. And he had promised a reward, saying, If two of you agree on earth about anything they ask for, it will be done for them by my Father in heaven. For where two or three gather in my name, there am I with them. The apostle Peter, provoked, asks how many times he should forgive his brother who sins against him, and when he proposes the question, should it be up to seven times? Jesus responds: Not up to seven times, but up to seventy times seven, that is, four hundred and ninety times, so that he should forgive his brother who sins against him as many times in a day as that brother cannot sin.
It is one thing to give pardon to a brother when he seeks it, that he may live with us in social charity, as Joseph to his brethren; and another to a hostile foe, that we may wish him good, and if we can do him good, as David mourning for Saul.
Then came Peter to Him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times? Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven. This is what Peter is asking: how many times, if one sins and then comes and begs forgiveness repentantly, should I forgive him? He added "sin against me," for if he sins against God, I, a layman, cannot forgive him, but only the priest who has this authority from God. But if he sins against me, then I will forgive him and he will be forgiven, though I am a layman and not a priest. He said, "until seventy times seven," not to limit forgiveness within a number, for it would be absurd for someone to sit and count the occasions until they numbered 490 (that is, seventy times seven). But what He means here is an infinite number, as if He were saying, "However many times he sins and repents, forgive him." He also tells us that we should be compassionate by means of the following parable.
Then Peter came to him and said: Lord, how often shall my brother offend against me, and I forgive him? Above he taught the order in which forgiveness should take place, namely, after correction and amendment; here he treats of the number, how often forgiveness should be given. First, therefore, Peter's question is set forth; secondly, Christ's response; thirdly, a similitude is introduced. The second is at Jesus said to him, etc.; the third at the kingdom of heaven is likened. He says therefore then Peter came. Then, namely, upon hearing this word, if your brother shall offend against you, etc., then Peter was moved as to whether he should forgive once or many times, and said how often shall my brother offend against me, etc., shall I not forgive until seven times? as if to say: up to seven times is from weakness, but more would be from malice. Therefore he asked whether he should forgive up to seven times. Likewise, he knew that which is stated in 2 Kings 5:10, that Elisha commanded Naaman to wash himself seven times in the Jordan; therefore he thought that he should forgive seven times.
There is no use in talking as if forgiveness were easy. We all know the old joke, "You've given up smoking once; I've given it up a dozen times." In the same way I could say of a certain man, "Have I forgiven him for what he did that day? I've forgiven him more times than I can count." For we find that the work of forgiveness has to be done over and over again. We forgive, we mortify our resentment; a week later some chain of thought carries us back to the original offence and we discover the old resentment blazing away as if nothing had been done about it at all. We need to forgive our brother seventy times seven not only for 490 offences but for one offence.
