You’ve definitely either said—or met someone who’s said—“I go to Mass, but I just don’t get anything out of it.”
Fr. Mike gets you. He’s said it too. But what he’s learned and cannot stop telling everyone is that Mass is not about you or getting anything out of it.
The heart of religion is worship, and the heart of worship is sacrifice.
Mass is not about what you can get, but what you can give to God that is due to him as Lord of the Universe.
