“If a man insults me, kills my father, my mother, my brother, and then gouges out my eye, as a Christian it is my duty to forgive him. We who are pious Christians ought to love our enemies and forgive them. We ought to offer them food and drink, and entreat God for their souls. And then we should say: ‘My God, I beseech Thee to forgive me, as I have forgiven my enemies.’”
St. Mark the Ascetic, Homilies, 2.48
“The forgiveness of insults is a sign of true love, free from hypocrisy. For thus the Lord also loved this world.”
St. Maximos the Confessor, Chapters on Love, 4.35
“A soul that is nurtured by hatred toward man can not be at peace with God, Who has said: If you forgive not men their sins, neither shall your Father forgive your sins (Matt. 6:15). If a man does not want to be reconciled, you must at least guard yourself from hating, praying with a pure heart for him, and speaking no evil of him.”
St. Silouan the Athonite
“Christ prayed for those that crucified Him: ‘Father, count not this sin against them; they know not what they do.’ Archdeacon Stephen prayed for those who stoned him so that the Lord would not judge this sin against them. And so we, if we wish to retain grace, must pray for our enemies. If you do not find pity on a sinner who will suffer in flames, then you do not carry the grace of the Holy Spirit, but rather an evil spirit; and while you yet live, you must free yourself from his clutches through repentance.”
St. Tikhon of Zadonsk, Journey to Heaven: Counsels on the Particular Duties of Every Christian
“Do we refuse to forgive? God, too, will refuse to forgive us. As we treat our neighbours, so also does God treat us. The forgiveness or unforgiveness of your sins, then, and hence also your salvation or destruction, depend on you yourself. For without forgiveness of sins there is no salvation. You can see for yourself how serious it is.”
“Prayer is food for the soul. Do not starve the soul, it is better to let the body go hungry. Do not judge anyone, forgive everyone. Consider yourself worse than everyone in the world and you will be saved. As much as possible, be more quiet.”
St. Peter of Damaskos, The Philokalia Vol. 3
“If we are not willing to sacrifice this temporal life, or perhaps even the life to come, for the sake of our neighbor, as were Moses and St. Paul, how can we say that we love him? For Moses said to God concerning his people, ‘If Thou wilt forgive their sins, forgive; but if not, blot me as well out of the book of life which Thou hast written’ (Ex. 32:32 LXX); while St. Paul said, ‘For I could wish that I myself were severed from Christ for the sake of my brethren’ (Rom. 9:3). He prayed, that is to say, that he should perish in order that others might be saved — and these others were the Israelites who were seeking to kill him.”
St. John of Kronstadt, My Life in Christ
“‘If he trespass against you seven times in a day, and seven times in a day turn again to you, saying, I repent; you shall forgive him’ (Lk. 17:4).
As the Searcher of hearts, the Lord knows that men are liable to very frequent trespass, and that, having fallen, they often rise up again; therefore He has given us the commandment to frequently forgive trespasses, and He Himself is the first to fulfill His holy word. As soon as you say from your whole heart, ‘I repent,’ you will be immediately forgiven.”
“You see very clearly that it is extremely difficult, and without God’s grace and your own fervent prayer and abstinence, impossible, for you to change for the better. You feel within yourself the action of a multitude of passions: of pride, malice, envy, greediness, the love of money, despondency, slothfulness, fornication, impatience, and disobedience; and yet you remain in them, are often bound by them, whilst the long-suffering Lord bears with you, awaiting your return and amendment; and still bestows upon you all the gifts of His mercy.
Be then indulgent, patient, and loving to those who live with you, and who also suffer from many passions; conquer every evil by good, and, above all, pray to God for them, that He may correct them—that He may turn their hearts to Himself, the source of holiness.
Do not help the Devil to spread his kingdom. Hallow the name of your Heavenly Father by your actions; help Him to spread His Kingdom on earth. ‘For we are laborers together with God.’
Be zealous of the fulfillment of His will on earth, as it is in heaven. Forgive them that trespass against you with joy, as a good son rejoices when he has a chance of fulfilling the will of his beloved father.”
