The miracle of holy fire has happened every Easter of each year in the church of the holy sepulchre for around 1000 years. It has been observed that the fire doesn’t cause burns, it stays at around 40 degrees Celsius for the first 30 minutes, and then returns to the properties of normal fire. Is this evidence for the Christian God or just a well done illusion?
