ELI5: Explain Like I'm 5

Feast of the Most Precious Blood

So, you know how blood is really important for our bodies because it carries oxygen to all our organs and helps us stay alive? Well, for some people who believe in God, they think that Jesus, who they believe is God's son, shed his blood to save people from their bad actions.

The Feast of the Most Precious Blood is a special day when these people remember and celebrate this idea. They do this by going to church and singing songs, praying, and listening to stories about Jesus and his sacrifice. They also often wear red clothes or decorate the church with red flowers, because red reminds them of blood.

Even though it might seem a little strange to you, it's really important for some people to remember and celebrate this act of love that they believe Jesus did for them.
