Luke 12:36

(Hom. 11. in Cant..) Or else, when the wedding was celebrated and the Church received into the secret bridal chamber, 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 cometh and knocketh, they may open to him immediately.

Now consider that He comes from the wedding as from a festival, which God is ever keeping; for nothing can cause sadness to the Incorruptible Nature.

(ubi sup.) But if a man has both of these, whosoever he be, nothing remains for him but that he should place his whole expectation on the coming of the Redeemer. Therefore it is added, And be ye like to men that wait for their Lord, when he will return from the wedding, &c. For our Lord went to the wedding, when ascending up into heaven as the Bridegroom He joined to Himself the heavenly multitude of angels.

(ubi sup.) For He comes when He hastens to judgment, but He knocks, when already by the pain of sickness He denotes that death is at hand; to whom we immediately open if we receive Him with love. For he who trembles to depart from the body, has no wish to open to the Judge knocking, and dreads to see that Judge whom he remembers to have despised. But he who rests secure concerning his hope and works, immediately opens to Him that knocks; for when he is aware of the time of death drawing near, he grows joyful, because of the glory of his reward.

Daily also in the heavens He betroths the souls of the Saints, whom Paul or another offers to Him, as a chaste virgin. (2 Cor 11:2.) But He returns from the celebration of the heavenly marriage, perhaps to all at the end of the whole world, when He shall come from heaven in the glory of the Father; perhaps also every hour standing suddenly present at the death of each individual.
