“When the new way is considered the only way, there is no continuity, fads become the new Gospel and in Paul’s words, the church is ‘blown to and fro by every wind of doctrine’.” — Loren Mead, in The Once and Future Church
The historical continuity and connections have meant the most the me, regardless of changes in the liturgy over time. The changes within various liturgies are no where near as radical as the changes in approaches to worship. As Mead suggests, emotional highs have taken the place of both the solemnity and the education within the liturgical worship services.
One should ask why emotional highs are important to God, why emotional highs are important to individual spiritual growth, and why (for many churches) worship has become inextricably tangled with emotional highs.
Why is my rock concert experience worth duplicating in church? Why is my Super Bowl experience worth duplicating in church? Our emotions ebb and flow but God remains constant.
