Tractates on the Gospel of John

^13. But as to David, why do I say that his prophecy extends to all nations, when we have just heard the psalm (and it is difficult to mention a psalm in which the same is not sounded forth)? But certainly, as I have said, we have been just singing, “Arise, O God, judge the earth; for You shall inherit among all nations.” And this is why the Donatists are as men cast forth from the marriage: just as the man who had not a wedding garment was invited, and came, but was cast forth from the number of the guests because he had not the garment to the glory of the bridegroom; for he who seeks his own glory, not Christ's, has not the wedding garment: for they refuse to agree with him who was the friend of the Bridegroom, and says, “This is He that baptizes.” And deservedly was that which he was not made, by way of rebuke, an objection to him who had not the wedding garment, “Friend, how are you come hither?” And just as he was speechless, so also are these. For what can tongue-clatter avail when the heart is mute? For they know that inwardly, and with their own selves, they have not anything to say. Within, they are mute; without, they make a din. But whether they will or no, they hear this sung even among themselves, “Arise, O God, judge the earth; for You shall inherit among the nations:” and by not communicating with all nations, what do they but acknowledge themselves to be disinherited?
