Clergy and Belief in God

According to a brief report in Ode Magazine, one in six Dutch clergy either do not believe in God or question whether God exists. Seven in 10 report their perspective on God has changed since they joined the ministry. Of the 680 Protestant and Catholic clergy in the study, belief in God was more common among younger than among older respondents. The study was performed by Hijme Stoffels, sociologist at Amsterdam's Free University, in conjunction with the broadcaster Ikon. (This info comes from Ode, March 2007, p. 18. I sought, but didn't find, a more academic source in English.)
