August 6 is a festival for Christians in both the east and the west recalling the event narrated in the gospels when Jesus's 'face shone like the sun, and his garments became white as light' (Matthew 17:1-8 // Mark 9:2-8 // Luke 9:28-36). This is a far more important feast in the Orthodox Churches and so we have an Orthodox theologian, Dr Andreas Andreopoulos, introducing the festival.
