"What would Jesus do bracelets" and fake "nails from the cross" necklaces sold during the movie "The Passion", represent some of the smaller items in evangelical subculture. Larger movements such as "the seeker sensitive" movement and Christian Contemporary Music are still others. It's where popular culture and Christianity comingle into an apostate stew. This doesn't mean that if a person buys a "Jesus loves you" magnet from the local Christian bookstore they are sinning, but there are definitely pitfalls to watch out for. This is one of the best articles I've seen on the subject.
The tragedy of the Evangelical Subculture is that people who have a sincere desire to follow Jesus get side tracked into a zeal for being a part of this worldly system. It is like joining a club. The club member begins to wear the clothes and trinkets bought at the "Christian" book stores; watch "Christian" TV and listen to "Christian" radio; buy the latest fad books that sweep the "Christian media"; subscribe to the "Christian" magazines; worship the "Christian" celebrities; use all the latest jargon promoted in the latest books by the celebrity authors.
This Evangelical subculture has played a major role in setting professing Christians up for deception. It seduces people to think and act like the subculture instead of reading the Bible for themselves and deriving their understanding from the Bible.
I totally agree.
