Sticking with the Princeton theme of this week, we’ve recently posted Archibald Alexander’s Evidences of the Christian Religion (1832). Not every modern Presbyterian will agree with his approach (although check out Paul Helseth’s "Right Reason” and the Princeton Mind for an “unorthodox proposal” regarding the Princetonian apologetic), but every stripe of apologist needs to be familiar with the external and internal evidences for Christianity. Alexander’s book, though written for a different era, still has much to teach Christians (and non-Christians!) today.
