Christ gave his life for you, and do you hold a grudge against your fellow servant? How then can you approach the table of peace? Your Master did not refuse to undergo every kind of suffering for you, and will you not even forgo your anger?… If you refuse to forgive your enemy you harm not him but yourself… There is no one God detests and repudiates more than the person who bears a grudge, whose heart is filled with anger, whose soul is seething with rage.
–Saint John Chrysostom (347-407)
