Catena Aurea · Lukasevangelium 12
Let your loins be girded about, and your lights burning; And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately. Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. And if he shall come in the second watch, or in the third watch, and find them so, blessed are those servants. And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through. Be ye therefore ready also: for the Son of man cometh at an hour when ye think not. PSEUDO-DIONYSIUS. (Dion. in Ep. ad Tit.) The “sitting down” is taken to be the repose from many labours, a life without annoyance, the divine conversation of those that dwell in the region of light enriched with all holy affections, and an abundant pouring forth of all gifts, whereby they are filled with joy. For the reason why Jesus makes them to sit down, is that He might give them perpetual rest, and distribute to them blessings without number. Therefore it follows, And will pass over (transiens) and serve them.
(ubi sup.) But to shake off the sloth of our minds, even our external losses are by a similitude set before us. For it is added, And this know, that if the goodman of the house had known what hour the thief would come.
