Easter is many things.
Easter is the day when the cosmic Christ, a thousand parsecs tall, crushed the serpent of Death beneath his heel and reclaimed all those it had held hostage.
Easter is Pascha, the second Passover, when Jesus led us out of bondage to sin and death and into a new land of life.
Easter is when the Powers that Be, who thought they had stamped out a dangerous radical movement, found it flamed back up beneath their feet.
Easter is when a group of friends, who thought the dearest among them was lost forever, found he had been given back to them.
All of these and many more. The common element is joy. May today be a day of joy for you and may it continue on through the year. Alleluia! He is Risen!
