Famous quotes containing the word spiritual:
“Yet the New Testament treats of man and man’s so-called spiritual affairs too exclusively, and is too constantly moral and personal, to alone content me, who am not interested solely in man’s religious or moral nature, or in man even.”
—Henry David Thoreau (1817–1862)
