The use of Liturgy, what I'll define as a prescribed set of practices, to enhance a person's relationship with their Savior is not specific to the Catholic Church. In the Protestant Church we don't call our practices Liturgy, but we do prescribe disciplines such as Bible reading, prayer, fasting, communion, etc. We believe those disciplines, when practiced faithfully, will draw us closer to Jesus.
Any action can become an empty ritual if our hearts aren't in the right place when we do them. If we read the Bible just so we can tell other people we've read the Bible, then what good is it doing? It only serves to puff us up with pride and we are deceiving ourselves.
