There's a superb blog post on Richard Floyd's blog, A Retired Pastor Ruminates, called, The Ministry and its Discontents: pastors in peril.
I've mentioned 'bullying, abusive congregations' on this blog before; Floyd has these in mind, but only partly. What his main concern is that where a church conducts a review of a pastor and doesn't conduct a review of itself, it's heading down a dangerous track. Early in the piece he writes:
Floyd is a man of considerable experience, and he's obviously been through the tough times (as some of his other blog posts have noted). Here he writes in an almost elder statesman style, as one who views the difficulties from the vantage point of acquired wisdom.
This blog post is essential reading.
