John Calvin Commentary Psalms 45:13

"The king`s daughter within [the palace] is all glorious: Her clothing is inwrought with gold." — Psalms 45:13 (ASV)

The daughter of the King is all glorious within. This verse may be understood in a twofold sense: either that the queen, not only when she appears in public before all the people but also when sitting in private in her own chamber, is always sumptuously dressed; or that the splendor and gorgeous appearance of her clothing is not merely for display, designed to dazzle the eyes of ordinary people, but is made of expensive and truly substantial material.

The prophet accordingly enhances the joyful and exalted condition of the queen by the fact that she has not only sumptuous clothing in which she may appear on particular occasions, but also for her ordinary and daily wear. Others interpret it in this sense: that all her glory consists in the king inviting her into his intimate presence, and they base this opinion on the grounds that immediately afterward, she is described as entering the king's chamber accompanied by a great and glorious train of followers.

This display of pomp exceeds proper moderation; yet, we are taught by it that while the Church is so richly adorned, it is not designed to attract human attention, but only for the pleasure of the King. If today the Church is not so richly adorned with that spiritual beauty in which the glory of Christ shines forth, the fault should be attributed to the ingratitude of people, who either through their own indifference despise the goodness of God, or else, after having been enriched by him, again fall into poverty and need.
