I don’t know of a mainstream fundamentalists school that doesn’t allow its faculty to participate in the Evangelical Theological Society or the Evangelical Philosophical Society. I do know of certain non-academics who question the legitimacy of this participation. Professor Mark Snoeberger has written an essay in which he offers insights as to the values of participation. He’s articulated a pretty decent rationale. Then Professor Tim Miller has reported on his own involvement–including a free download of the paper he read this year. Check them out.
