For if we, going about on the earth which is familiar and well known to us, being encompassed with a body, when we are journeying in a strange road, know not which way to go unless we have some one to lead us; how should the soul, being rent away from the body, and having gone out from all her accustomed region, know where to walk without one to show her the way?
-St. John Chrysostom, Homily 28 on Matthew 8, 4th Century
