Here's a great passage from St. John Chrysostom on the Parable of the Unrighteous Steward that shaped my thinking in preparing yesterday's sermon:

You are an administrator of things that are another's ... Upon you has been bestowed but the right of their brief and passing use. Cast then from your soul the pride of dominion, and put on instead the modesty and humility of a steward.
