There is a very real sense in which everything that is is sacred. We say, or at least said, that life is sacred; motherhood is sacred, and so on. Far be it from me to deprecate this usage. For does not the root evil of our time, the secularization of life, he precisely in atrophy of the religious sense? It was this very tendency of the historical process which caused voices to be raised amid the wilderness of nineteenth-century industrialism, reaffirming the holiness not only of God’s creation but also of the works of man.
Holy: holiness: here we have le mot juste. We say God is holy. The word is inadequate but not erroneous. It would never occur to us to say God is sacred: not only would that be erroneous, it would be absurd. Sacred to what? This question alone is enough to make it clear that whereas the concept of holiness is absolute, that of the sacred is relative. It might be said that holy is predicated of God and of his gifts to us, sacred of our gifts to him.
Whatever is sacred is holy, but not all that is holy is sacred, save in the very diluted sense of meriting our respect. Be it clear from the outset that in these pages the word is not used in this its most generic meaning but in the truest and most positive sense by which sacred signifies set apart by man for the worship of God.
