Phil Johnson has a great post on the trend in evangelical exhibitionism here.  The last paragraphs are particularly pertinent:

It's yet another sign of evangelicalism's growing conformity to worldly values and worldly behavior. The various evangelical coalitions and young Reformed movements that looked so encouraging five years ago have done more to encourage and enable this kind of exhibitionism than to challenge it. These things ought not to be.

How bad will it have to get before true leaders in the church and in the various gospel-centered movements find their voices and start calling the church--and some of these out-of-control exhibitionist preachers--to repentance? I for one hope we get an answer to that question before very long. I pray for it every day.

I suspect, if recent history is any safe guide, that Phil will find that this post leaves him being regarded by those to whom he is referring as part of the problem, not part of the solution.  It may not be his wedding day, but it is his Kane moment -- not Charlie this time, but Will.
