And if you should hear a mocker by chance when you do not wish to hear, sign yourself with the cross of light, and run from that place like an antelope. Where Satan lodges, Christ will certainly not dwell; a spacious dwelling for Satan is the man who mocks his neighbor; a palace of the Enemy is the heart of the mocker. Satan does not desire to add any other evil to it. Mockery is sufficient for him to supply the place of all. - Saint Ephrem of Syria
