4The critique of Willow Creek as a “dated” and “Boomer” model can be found in Sally Morganthaler, “Out of the Box: Authentic Worship in a Postmodern Culture,” Worship Leader (May-June 1998): 24ff. This and an interview with musician Fernando Ortega in Prism (Nov-Dec 1997) are indications of some major cracks in the foundation of evangelical assumptions about what kind of services will reach young secular people. However, if a church abandons “Boomer” contemporary music for more alternative rock, won’t it be in the same position in another ten to fifteen years that Willow Creek is in now? More historic worship forms have a better claim to durability.
