Christian worship, especially in the Reformed lineage, has always been about a great deal more than what we do in church on Sunday. “Work is worship” my parents used to say (except on Sunday). Service is worship. And there was a great deal of talk about sacrificing—especially when I became a teenager—referenced to the first verse of Romans 12.
This wide definition of worship, in my experience, has been both a great gift of our tradition and a sorry excuse for impoverished formal worship.
