Wisdom out of Russian Orthodox tradition:
“A man who is wrathful with us is a sick man; we must apply a plaster to his heart – love; we must treat him kindly, speak to him gently, lovingly. And if there is not deeply-rooted malice against us within him, but only a temporary fit of anger, you will see how his heart, or his malice, will melt away through your kindness and love – how good will conquer evil.”
John of Kronstadt, Russian Orthodox archpriest. 1829-1908
