I think the phrase masturbatory worship is very apropos. There is often a lack of community, of recognition or responsiveness to the others present; and a strong prioritization of my personal experience and preference—indeed, a genuine selfishness in worship rather than the give-and-take that belongs within the communion of saints, the Body of Christ. Christianity is relational—us with God in Christ; us with others, united in Christ. The minimally interactive, highly sensual nature of modern praise worship is not relational in the same way; and in a way, intentionally so–relationships are hard work.
