St. John Chrysostom: On the Feast of Theophany, Part 1

We shall now say something about the present feast.  Many celebrate the feast days and know their designations, but the cause for which they were established they know not. Thus concerning this, everyone knows that the present feast is called Theophany; but what this is, and whether it be one thing or another, they know not. And this is shameful—every year to celebrate the feast day and not know its meaning.

First of all therefore, it is necessary to say that there is not one Theophany, but two: the one actual, which already has occurred, and the second in the future, which will happen with glory at the end of the world. About this one and about the other you will hear today from Paul, who in conversing with Titus, speaks thus about the present: “The grace of God hath revealed itself, having saved all mankind, decreeing, that we reject iniquity and worldly desires, and dwell in the present age in prudence and in righteousness and piety.”  And about the future: “Awaiting the blessed hope and glorious appearance of our great God and Savior Jesus Christ” (Titus 2:11-13). And a prophet speaks thus about this latter: “The sun shalt turn to darkness, and the moon to blood at first, then shalt come the great and illuminating Day of the Lord” (Joel 2:31).
