For most people, Easter is now just another break where you may get a couple of extra days off work. I don't think that for most people any of the religious festivals have much meaning beyond that. Christ-mass is now just the commercial obscenity of Xmas and I doubt there are very many people who know the slightest thing about the meanings of, say, Epiphany, Lent or Advent (unless in the latter case it's a calendar full of chocolates).
I was fascinated by The Narrow Road's account of Easter's origins - bit like the early Church taking over Saturnalia for Christmas! Except that, even given the problems about dating the crucification, it does seem that Jesus was crucified around about what we call Easter.
In my church-going days Easter was a time for reflection on the meaning of the Passion and a celebration of our redemption by Christ's sacrifice on the Cross. Today, I think it's probably appropriate for contemplating just the meaning of Christ's teachings, as far as we can get at what they were, and how we might apply them in our lives to our own and others benefit.
to get people thinking!
