Catena Aurea

THEOPHYLACT. Or since the watches are the hours of the night which lull men to sleep, you must understand that there are also in our life certain hours which make us happy if we are found awake. Does any one seize your goods? Are your children dead? Are you accused? But if at these times you have done nothing against the commandments of God, He will find you watching in the second and third watch, that is, at the evil time, which brings destructive sleep to idle souls.

GREGORY. (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.

THEOPHYLACT. Some understand this thief to be the devil, the house, the soul, the goodman of the house, man. This interpretation, however, does not seem to agree with what follows. For the Lord’s coming is compared to the thief as suddenly at hand, according to the word of the Apostle, The day of the Lord so cometh as a thief in the night. (1 Thess. 5:2.) And hence also it is here added, Be ye also ready, for the Son of man cometh at an hour when ye think not.

GREGORY. (Hom. 13. in Ev.) Or else; unknown to the master the thief breaks into the house, because while the spirit sleeps instead of guarding itself, death comes unexpectedly, and breaks into the dwelling place of our flesh. But he would resist the thief if he were watching, because being on his guard against the coming of the Judge, who secretly seizes his soul, he would by repentance go to meet Him, lest he should perish impenitent. But the last hour our Lord wishes to be unknown to us, in order as we cannot foresee it, we may be unceasingly preparing for it.
