Question: Why does the procession on the night of Pascha [Easter] go counter-clockwise? In general, does going clockwise or counter-clockwise play any role in [Christian] Orthodox rites?
Answer: Performing the procession, the Orthodox go out to meet the sun, inasmuch as the Savior of the world, Jesus Christ, by the definition of the Church, is the Sun of righteousness. We go out to meet our Lord.
