How many there are who still say, 'I want to see His shape, His image, His clothing, His sandals.' Behold, you do see Him, you touch Him, you eat Him! You want to see His clothing. He gives Himself to you, not just to be seen but to be touched, to be eaten, to be received within .... Let all of you be ardent, fervent, enthusiastic. If the Jews stood, shoes on, staff in hand, and eating in haste, how much more vigilant should you be. They were about to go to Palestine; ... you are about to go to heaven.
Saint John ChrysostomIf then we have Angels, let us be sober, as though we were in the presence of tutors; for there is a demon present also.
Saint John Chrysostom
