Great post by Doug Wilson over at his blog...
The seraphim who constantly adore Him do not worship before the throne, saying, "Love, love, love." Nor do they say, "Just, just, just." They do not cry out, "Good, good, good." Although these are all attributes of God, His attribute that fulfills and permeates all the others is His Holiness. The seraphim cry, "Holy, Holy, Holy" (Is. 6:3; cf. Rev. 4:8).
Certain attributes of God, like His omniscience, are called incommunicable attributes. This is because creatures cannot partake of them. But holiness, for all its ultimacy, is not in this category. There is such a thing as communicated holiness. This attribute is shared to us by the grace of God. We are called to be saints (1 Pet. 1:13-16).
