Have you ever heard people say "Christ is risen!" and "He is risen indeed!" to each other during Easter time? This is called the Paschal Greeting.
It’s a special way for Christians to greet each other during the Easter season. Christians believe that Jesus rose from the dead on Easter Sunday, so they are happy and excited to celebrate this important event.
When a person says "Christ is risen!" to another person, the other person responds with "He is risen indeed!" It's like a secret code between Christians that reminds them of the resurrection of Jesus.
Christians usually share the Paschal Greeting by saying it to each other in person, over the phone or online during the Easter season. It's a way for them to show that they believe in Jesus and that they are excited about the new life that he brings.
