When I recently asked a teenage guy this question, he responded quickly with,“Bcause we get a day off school?”
It’s sad, isn’t ?
A universally acceptable Christian emblem would obviously need to speak of Jesus Christ, but there was a wide range of possibilities. Christians might have chosen the crib or manger in which the baby Jesus was laid, or the carpenters bench at which he worked as a young man in Nazareth, dignifying manual labor, or the boat from which he taught the crowds in Galilee, or the apron he wore when washing the apostles’ feet, which would have spoken of his spirit of humble service. Then there was the stone which, having been rolled from the mouth of Joseph’s tomb, would have proclaimed his resurrection. Other possibilities were the throne, symbol of divine sovereignty, which John in his vision of heaven saw that Jesus was sharing, or the dove, symbol of the Holy Spirit sent from heaven on the Day of Pentecost. Any of these seven symbols would have been suitable as a pointer to some aspect of the ministry of the Lord. But instead the chosen symbol came to be a simple cross. Its two bars were already a cosmic symbol from remote antiquity of the axis between heaven and earth. But its choice by Christians had a more specific explanation. They wished to commemorate as central to their understand of Jesus neither his birth nor his youth, neither his teaching nor his service, neither his resurrection nor his reign, nor his gift of the Spirit, but his death, his crucifixion.
