The ministerial work must be carried on purely for God and the salvation [1] of souls, not for any private ends of our own...Hard studies, much knowledge, and excellent preaching, if the ends be not right is but more glorious hypocritical sinning.
--Richard Baxter (12 November 1615 – 8 December 1691, English Puritan church leader, poet, hymn-writer, and theologian).
