The exact range and character of Smith's religious beliefs is the subject of some controversy, and the path he took in negotiating what seems to have been the poles in his religious universe - the radical skepticism of his friend David Hume and the Christian Stoicism of his mentor, Francis Hutcheson - is unknown to us. It is presumptuous, and perhaps a little dangerous, to lean too heavily upon Smith's religious beliefs to draw conclusions about his economic analysis.
In any event, Smith seems to have been a member of the Presbyterian Church, gave generously during his life, and left large sums of money to charity upon his death.
