Some of the tidbits from Notes for Pascha & Bright Week:
• We greet one another during the entire Paschal season (which lasts 40 days) with the words: “Christ is risen!” and the response to the greeting is: “Indeed, He is risen!” . . .
• During Bright Week, our prayers in church and at home are sung and not read as we sing all week the feast of the risen Christ: Christ is risen!
• During Bright Week, our morning and evening prayers are replaced by the singing of the short service of the Hours of Pascha (see your prayer books or see below): Christ is risen!
• During Bright Week, we do not read from the psalter at home or in church for the prophecies have been fulfilled: Christ is risen! . . .
• During the Paschal season we begin all of our prayers at home and in church by singing the troparion of Pascha: “Christ is risen from the dead, trampling down death by death, and upon those in the tombs bestowing life!”
• During the Paschal season and extending to Pentecost, we do not pray “O Heavenly King, the Comforter, the Spirit of Truth…” for the Comforter comes on Pentecost. Christ is risen!
• And most important of all: “A Pascha worthy of all honor has dawned for us. Pascha! Let us embrace each other joyously!…This is the day of resurrection. Let us be illumined by the feast. Let us embrace each other. Let us call ‘Brother’ even those who hate us, and forgive all by the resurrection, and so let us cry: Christ is risen from the dead, trampling down death by death, and upon those in the tombs bestowing life!” “And unto us He has given eternal life. Let us worship His resurrection on the third day!”
