2 Samuel 6:14

And that David danced before the Lord does in no way encourage faithful Christians to take seats in the theater. He did not distort his body in obscene movements and dance out the drama of Grecian libido.… Therefore, no approval whatever is given for spectators of illicit things.

For our vows are celebrated when the church is united to Christ, as John says: "The one who has the bride is the bridegroom." Because of this marriage, therefore, it behooves us to dance, for David, at once king and prophet, is also said to have danced before the ark of the covenant with much singing. In high rejoicing he broke into dancing, for in the Spirit he foresaw Mary, born of his own line, brought into Christ's chamber, and so he says, "And he, like a bridegroom, will come forth from his chamber." Thus he sang more than the other prophetic authors because, gladder than the rest of them, by these joys he united those coming after him in marriage. And, by inviting us to his own vows in a more charming way than usual, having danced with such joy in front of the ark before his marriage, he taught us what we ought to do at those other vows. The prophet David danced, then. But what would we say that the ark was if not holy Mary, since the ark carried within it the tables of the covenant, while Mary bore the master of the same covenant? The one bore the law within itself and the other the gospel, but the ark gleamed within and without with the radiance of gold, while holy Mary shone within and without with the splendor of virginity; the one was adorned with earthly gold, the other with heavenly.

But because secret pride of heart is reproved by this, which Eliu says, "All who seem to themselves to be wise will not dare to contemplate Him"; it seems good to observe what great gifts of virtues David had obtained, and in all these with how firm a humility he maintained himself. For whom would it not puff up, to break the mouths of lions; to rend asunder the arms of bears; to be chosen, when his elder brethren had been despised; to be anointed to the government of the kingdom, when the King had been rejected; to slay with a single stone Goliah who was dreaded by all; to bring back, after the destruction of the aliens, the numerous foreskins proposed by the King; to receive at last the promised kingdom, and to possess the whole people of Israel without any contradiction? And yet, when he brings back the Ark of God to Jerusalem, he dances before the Ark, mingled with the people, as though forgetful that he had been preferred to them all. And because, as is believed, it had been the custom of the common people to dance before the Ark, the king wheels round in the dance, in service to God. Behold how he whom the Lord preferred specially above all, contemns himself beneath the Lord, both by equalling himself with the least, and by displaying abject behaviour. The power of his kingdom is not recalled to his memory; he fears not to be vile in the eyes of his people, by dancing; he remembers not, before the Ark of Him Who had given him honour, that he had been preferred in honour above the rest. Before God he performed even the extremest vilenesses, in order to strengthen, by his humility, the bold deeds he had performed in the sight of men. What is thought by others of his doings, I know not; I am more surprised at David dancing, than fighting. For by fighting he subdued his enemies; but by dancing before the Lord he overcame himself. And when Michal, the daughter of Saul, still mad with pride at her royal descent, despised him when humbled, saying, "How glorious was the king of Israel to-day, uncovering himself before the handmaids of his servants, and made himself naked, as though one of the buffoons were naked"; she immediately heard, "As the Lord liveth, I will play before Lord, Who hath chosen me rather than thy father." And a little after he says, "And I will play, and I will become more vile than I have been, and I will be humble in mine own eyes." As…
