Christian-Jewish reconciliation is when Christians and Jews try to get along better and be friends. Christians are people who follow the teachings of Jesus and Jews are people who follow the teachings of Moses. They both believe in God, but they have different traditions and ways they worship.
Sometimes in the past, Christians and Jews weren’t very friendly with each other and there was a lot of fighting. But today, people from both religions work together to make peace and show kindness towards each other. They try to forgive the past and look to the future with friendship and understanding. When Christians and Jews become friends, it’s called Christian-Jewish reconciliation.
