Why Do Catholics Have to Attend Sunday Mass?

When we skip Mass on Sunday, we are violating our covenant with God. We are saying to God, 'I don't need to be united to you. I don't need to worship you.' It may seem innocent, but we are actually declining His marriage proposal. We are not showing up for our own wedding.

When we make a decision to deny His invitation to covenant we are saying we don't want a relationship with Him. Because our God loves us and is a gentleman, he allows us to do this.

However, it’s a grave sin to miss Mass.
