Via Shaun Groves, from "An Atheist in the Pulpit" at Psychology Today:
Charles Templeton, the late Canadian evangelist turned journalist, argued that a disjunction between what clergymen say publicly and what they believe privately is so common that serious cognitive dissonance comes with the territory. “Most intelligent clergymen preach to the right of their theology,†Templeton wrote..."They are more conservative in the pulpit than they are in private conversation or when counseling a parishoner.â€
Shaun adds:
The article hurls loads of anecdotal evidence at us but none of it supports the theory that this cognitive dissonance is the reason some pastors deconvert. The evidence instead points to a dissatisfaction with the way they’ve been treated by Christians and with various social/moral positions taken by their denomination.
Still, poor argument making aside, they’re right about one thing: The beliefs held by some (many?) pastors are to the left of those they lead and keeping that a secret can jack one up.
Maybe it's because I hang around the mainline, but I don't see that; the pastors I know, where they live is where they preach. I'd be interested to know on what basis this assertion is made.
