On Good Friday, next week, the story of Jesus' arrest, trial and crucifixion will be read in Churches across the country. In the Passion according to St John, Pontius Pilate famously asks: what is truth? An intriguing moment which resonates with modern times. We might well ask the same question today: an era of 'alternative facts' and 'fake news'; or so we are told.

Religions claim they hold the 'truth', but religious belief cannot be proved like the sort of truth which is based on empirical evidence. What are some of the religious understandings of truth? And what role does religion have to play in a so-called 'post-truth' world?
