Edmund S. Lorenz,
The Singing Church: The Hymns It Wrote and Sang
“ In so far as a hymn is a transcript of a genuine conviction, intensified by emotion, or of a profound experience, it is literature. There have gone into it vision, feeling, imagination, sincerity, intimate experience—an appropriation of the influences life offers a soul that gazes upon it with wide-open eyes. It is not the measure or the rhyme that makes literature of a hymn. A bald formulation in metrical form of doctrines dissected by metaphysical processes may be called a hymn by courtesy, but it is not literature any more than would be a textbook on mathematics. ”
