Section 15
On the Ecclesiastical Hierarchy · Pseudo-Dionysius the Areopagite
Meanwhile, the whole order of the Priests having been collected together in hierarchical order, and communicated in the most Divine mysteries, finishes with a holy thanksgiving, after having recognized and sung the favours of the works of God, according to their degree. So that those, who have not partaken and are ignorant of things Divine, would not attain to thanksgiving, although the most Divine gifts are, in their essential nature, worthy of thanksgiving. But, as I said, not having wished even to look at the Divine gifts, from their inclination to things inferior, they have remained throughout ungracious towards the boundless graces of the works of God. "Taste and see," say the Oracles, for, by the sacred initiation of things Divine, the initiated recognize their munificent graces, and, by gazing with utmost reverence upon their most Divine height and breadth in the participation, they will sing the super-celestial beneficent works of the Godhead with gracious thanksgiving.
