Abstract: Someone is rational in following a certain religious way to attain a certain goal only if he believes that it is more probable that following that way will achieve that goal than that following any other way will achieve a similar goal (one that has a similar understanding of salvation and Heaven). In view of the importance of the issue, people should devote time to investigating the claims of different religions and consider the worth of the different goals that they officer. This will include considering the relative probabilities of different claims to have a revelation, which depend both on the moral plausibility of the purported revelation and on any miraculous authentication it purports to have (e.g. the Resurrection of Jesus authenticating his teaching). Which way a person should follow depends both on his judgement of the relative probability of the creeds of rival religions and on his judgement of the worth of the goals that they offer.
