 His sermons were clear, vigorous expositions of a moderate Calvinism, in which metaphysical argument and practical morality are happily blended.He was very supportive of foreign missions, which he supported in the General Assembly - famously beginning a response to an opponent of such missions ""Moderator, rax me (that is, hand me) that bible"".His books, etc., show him to have been very prolific and to have been keenly interested in the politics of the day.
