Easter is the greatest high feast on the Catholic/Christian calendar. Every other Sunday is rooted in Easter. It is so huge that the Church celebrates an octave (8 days) to prolong the JOY of the Resurrection of Our Lord, Jesus.
Easter celebrates the defeat of death and the hope of salvation. The Easter Vigil begins in darkness. The celebrant blesses the new fire outside the church expelling the darkness. The new Paschal Candle, the symbol of the light of Christ, is lit from the fire. The celebrant proceeds into the church to continue lighting all the candles held by the faithful, illuminating the darkened church with the light of Christ. The Easter Proclamation (EXSULTET) is sung. It is a majestic proclamation of the Resurrection of Christ. The Liturgy of the word moves us through the outstanding deeds of the history of salvation. The Gloria is then sung with the bells being rung, praising God the Father and the Lamb, Jesus.
Alleluia, Alleluia, Alleluia becomes our song through the Easter season of 50 days.
Luke24:34 The Lord s risen indeed!
