The miracle occurs every year on the Orthodox Easter Saturday. There are many types of Orthodox Christians: Syrian, Armenian, Russian and Greek Orthodox as well as Copts. In the Holy Sepulchre Church alone there are 7 different Christian Denominations. The Orthodox Easter-date is fixed according to the Julian Calendar, and not the usual Western European Gregorian calendar, which means that their Easter normally falls on a different date than the Protestant and Catholic Easter.
"I find my way through the darkness towards the inner chamber in which I fall on my knees. Here I say certain prayers that have been handed down to us through the centuries and, having said them, I wait. Sometimes I may wait a few minutes, but normally the miracle happens immediately after I have said the prayers. From the core of the very stone on which Jesus lay an indefinable light pours forth. It usually has a blue tint, but the color may change and take many different hues. It cannot be described in human terms. The light rises out of the stone as mist may rise out of a lake it almost looks as if the stone is covered by a moist cloud, but it is light. This light each year behaves differently. Sometimes it covers just the stone, while other times it gives light to the whole sepulchre, so that people who stand outside the tomb and look into it will see it filled with light. The light does not burn I have never had my beard burnt in all the sixteen years I have been Patriarch in Jerusalem and have received the Holy Fire. The light is of a different consistency than normal fire that burns in an oil lamp.
"At a certain point the light rises and forms a column in which the fire is of a different nature, so that I am able to light my candles from it. When I thus have received the flame on my candles, I go out and give the fire first to the Armenian Patriarch and then to the Coptic. Hereafter I give the flame to all people present in the Church."
