Who else but St John the "Golden-mouthed" Chrysostom?
“Our warfare does not make the living dead, but rather makes the dead to live, because it is conducted in the spirit of meekness and humility. I persecute by word, not by acts. I persecute heresy, not heretics. It is mine more to be persecuted, than to persecute. So Christ was victorious as a Crucified, and not as a crucifier.”
"And should you hear any one in the public thoroughfare, or in the midst of the forum, blaspheming God; go up to him and rebuke him; and should it be necessary to inflict blows, spare not to do so. Smite him on the face; strike his mouth; sanctify your hand with the blow, and if any should accuse you, and drag you to the place of justice, follow them thither; and when the judge on the bench calls you to account, say boldly that the man blasphemed the King of angels! For if it be necessary to punish those who blaspheme an earthly king, much more so those who insult God."
Different circumstances call for different methods. St John has it covered. Gently correct and guide the ignorant and good-willed, smite the blasphemer and wolf seeking to devour the flock.
