We don't really use the Spirit Filled Life tracts either. We do use a really wide variety of materials from both inside and outside CCC. Stuff from Os Guiness, Rick Warren, bible studies from my PCA church, Francis Schaeffer, Your Life in Christ (CCC), Armand Nicholi, Satisfied (CCC), Sacred Romance (Curtis & Eldridge), the Alpha Study. You seem to see CCC as a monolithic organization with strict adherance to certain CCC materials. That isn't my experiance.
