God the Father raises Jesus from the dead.
Even though Easter is not the beginning of the Roman Catholic liturgical year, it is the highpoint of the year. Easter is the celebration of the paschal mystery, coming from the word pascha, which means “Easter.”
There are a number of aspects of the paschal mystery incorporated into the celebration of Easter that makes it so embracive. One is the presence of the risen Christ beyond the time of his human journey.
The Resurrection—indeed the whole of the paschal mystery—is not a past event that we merely commemorate. It is part of our lives today, part of the life of the Church since the days of the community that was formed around Jesus of Nazareth, continuing and being built up in love as you stand in your parish assembly each Sunday.
