Theophylact of Ohrid
Catena Aurea · Lukasevangelium 18
And he spake a parable unto them to this end, that men ought always to pray, and not to faint; Saying, There was in a city a judge, which feared not God, neither regarded man: And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary. And he would not for a while: but afterwards he said within himself, Though I fear not God, nor regard man; Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me. And the Lord said, Hear what the unjust judge saith. And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth? It follows, And there was a widow in that city.
As if He said, If perseverance could melt a judge defiled with every sin, how much more shall our prayers incline to mercy God the Father of all mercies! But some have given a more subtle meaning to the parable, saying, that the widow is a soul that has put off the old man, (that is, the devil,) who is her adversary, because she approaches God, the righteous Judge, who neither fears (because He is God alone) nor regards man, for with God there is no respect of persons. Upon the widow then, or soul ever supplicating Him against the devil, God shews mercy, and is softened by her importunity. After having taught us that we must in the last days resort to prayer because of the dangers that are coming, our Lord adds, Nevertheless, when the Son of man cometh, shall he find faith on the earth?
