Origen of Alexandria : Watch therefore, for you do not know at what hour your Lord will come. Not giving "sleep to the eyes" of our soul nor "slumber to the eyelids," so that we may await either our own end or the end of the age, whether that we should depart from this life or that this world should be brought to its consummation for us. But someone will ask how the Lord, established as present among the disciples, speaks thus, as though not present but about to come, saying to them: watch, for you do not know at what hour your Lord will come. And the one who is more simple will say that he spoke this discourse concerning the second coming, in which he was to come. But another will say that he was speaking of the intelligible coming of the Word, still to come into the understanding of the disciples, because it was not yet in their understanding in the way it was going to be: since (as he shows through this passage) in those who watch he works the day of his coming in the soul of those who are illumined by the true light of him who comes to their souls. Now the householder is the understanding of the man, and his house is his soul; but the thief, who comes suddenly while the householder sleeps and breaks into the house, is, I think, the devil or every contrary word, according to what the evangelist John teaches us, saying in this manner: "amen amen I say to you, he who does not enter through the door into the sheepfold but climbs up another way, that man is a thief and a robber". As, therefore, he who "enters through the door into the sheepfold" is "the shepherd of the sheep", for whom "the doorkeeper opens", but "he who does not enter through the door but climbs up another way is a thief and a robber", so the lord of the house enters into it confidently "through the door" when he wills, rewarding the one who watches; but the thief, being a thief, does not enter into the house to the soul of the negligent by the natural entrance, but (as one who has already broken into it) first destroying certain natural buildings of his soul and natural understandings, in him who has not watched — the things which God the Word had built. And having entered through that very breach, the thief plunders it, disarming the understanding, when, despoiling the householder who does not watch, "he will distribute his spoils". But sometimes someone catches the thief in the very act of breaking in, and seizing him as one having his own weapons, he strikes the thief, and, confuting the word that breaks in, he kills it, when, though killing, he is not reckoned a murderer, killing it without any delay. But if not in his own presence, yet in the presence of him who makes all hidden things manifest, someone catches him who has stolen his goods, and understands him and refutes him (that is, kills him), he has no pardon, the thief being dead and made manifest: for he too will die. And see whether perhaps the law of Moses signifies some such thing, saying: "but if the thief is found in the very breaking in and, being struck, dies, there is no bloodguilt for him; but if the sun has risen over him, he is guilty: he shall die for it". For he who, before he does the evil, recognizes the evil and crushes it in himself, is the one who catches and kills it in himself, while it is being broken in upon by it. But he who, after he has done the evil, although he refutes it, is seen to have caught the evil outside himself and to have killed it outside his house — it profits him nothing, for he has been made guilty of death. For after any man has sinned and turned back into himself, the divine understanding which is in us illumines him like a light, so that we may understand that the evil we have committed was to our own condemnation, not to our salvation. Yet in the text of this Gospel of which we are speaking, the thief comes not by day, when the soul of the earnest man has been illumined by the sun of righteousness, but by night and in the time while malice still remains. — COMMENTARY ON Matthew 59
