Our venerable and God-bearing Father Maximus the Confessor (ca. 580-662) was an Orthodox Christian monk and ascetical writer known especially for his courageous fight against the heresy of Monothelitism. His feast days in the Church are celebrated on January 21 and, for the translation of his relics, on August 13.
“If you bear a grudge against anyone, pray for him and you will stop the passion in its tracks.
By prayer you separate the hurt from the memory of the evil which he did you and in becoming loving and kind you completely obliterate passion from the soul.
On the other hand, if someone else bears you a grudge, be generous and humble with him, treat him fairly, and you will deliver him from the passion.”
