Richard Swinburne's tetralogy on Christian doctrine, together with his earlier trilogy on the philosophy of theism, is one of the most important apologetic projects of recent times. This paper focuses on some difficulties with this project that stem from Swinburne's use of confirmation theory. Arguably, the problem of dwindling probabilities, pointed out by Plantinga, has not been solved. The paper is principally focused, however, on the ways in which Swinburne's confirmation theory contributes to his comparative neglect of the personal, existential dimension of Christianity. A solution for these difficulties is suggested but not elaborated.
