When I was a parish priest, the local state primary school would sometimes bring children to visit the church. One of the things I discovered quite quickly was that Christianity was taught alongside other faiths, and this integration involved focusing on various festivals from different religions. For Christianity, the key focus was on Christmas and Easter. Thus, the children could look at the statue of Mary and Jesus and knew who they were. Similarly, they could look at a crucifix and tell me that this was Jesus and that he died on a cross, although the Resurrection did not seem to figure in the story.
