For those of the Christian faith, the Easter holiday celebrates the central events of their faith.
Christians believe that Jesus Christ, the Son of God, came to Earth, died for the sins of Mankind, and arose again on the 3rd day, that is, Easter Day.
I myself am a lapsed Catholic, and no longer think much on these beliefs. But I do remember the teachings - this central tenet of the faith, and its message of caring and sacrifice. I remembered thinking of it as a good thing. And I believe that sincere faith in those teachings remains valuable to Christians and I respect and admire their faith.
So, I wish all Christians a Happy Easter.
