Religious background: Jesus Christ left his last instructions to his disciples at the last supper. He raised the bread in his hand, thanked them, and then broke it for his disciples to eat. So he raised his glass, thanked him and gave it to his disciples to drink. Jesus said to them, This is my bone and my flesh. Now that you have eaten and drunk, my flesh and blood are in your bodies, so you will remember me in the future. Therefore, later Christian churches will hold such a cake-breaking ceremony at a specific time to commemorate Jesus Christ. Bread-breaking ceremony is one of the most important ceremonies in Christian church. At present, churches headed by Christ, such as Catholicism and Protestantism, regularly hold such ceremonies to commemorate Christ's life and thank him for his contribution to mankind.
