“If you anger when you yourself are offended, your anger is unclean.
It’s unseemly to become angry in one’s own defense.
Resisting evildoers is another matter, however, when it’s in defense of serious spiritual matters, when our holy faith,Orthodoxy, is concerned.
Then it’s your duty. To think of others, to counter the blasphemers in order to defend one’s neighbor — this is pure, because it is carried out in love.”
Elder Paisios
