Let your waists be girded about, and your lamps burning;
All Commentaries on Luke 12:35 Go To Luke 12
Gregory of Nyssa
AD 394
Or else, when the wedding was celebrated and the Church received into the secret bridal chamber, in the angels were expecting the return of the King to His own natural blessedness. And after their example we order our life, that as they living together without evil, are prepared to welcome their Lord's return, so we also, keeping watch at the door, should make ourselves ready to obey Him when He comes knocking; for it follows, that when he comes and knocks, they may open to him immediately.
For the sake then of keeping watch, our Lord advised above that our loins should be girded, and our lamps burning, for light when placed before the eyes drives away sleep. The loins also when tied with a girdle, make the body incapable of sleep. For he who is girt about with chastity, and illuminated by a pure conscience, continues wakeful.
