Okay kiddo, let me tell you all about the Corpus Christi play. So, back in the old days, in some parts of the world, there was a special holiday called Corpus Christi. It celebrated something really important to Christians - the idea that bread and wine can become Jesus' body and blood.
During this holiday, people like to put on a special play to tell the story of Jesus and his followers. It's called the Corpus Christi play because it's all about this special day. People dress up in costumes and act out scenes from the Bible. It's like a really big and fun play!
The play usually starts with the story of how God created the world and then goes on to tell about Jesus and the things he did when he was alive. The actors might dress up as angels, disciples or other important characters from the Bible.
In the end, the play usually ends with a big celebration where everyone gets together to thank God and eat some yummy food. It's a really fun and special time for everyone who takes part in it.
So, that's the Corpus Christi play - a special play that celebrates an important Christian holiday and tells the story of Jesus and his followers.
