The Message of Easter is kept more in the background of the holiday than that of Christmas.
Without faith, the events speak of failure, with faith, they speak.
For the Easter story to work as a joyous occasion you have to accept two stories - the death of Jesus - a negative event - and then the resurrection of Jesus - which requires faith.
After all, this is not the joyous welcoming of a baby with the giving of gifts, this is the brutal death of a young man, stripped of any gifts and dignity.
