Chauncy did indeed wind up a staunch unitarian. At the time of the old light/new light controversy, I believe Chauncy was a pretty committed confessional congregationalist.

With respect to Whitefield, I definitely agree. Reading his sermons and journals seem to confirm the consensus of most Reformed scholarship. Nevertheless, I don't think its Whitefield's theology that presents a problem. I think significant criticism has been leveled at Whitefield for 1.) un-churchly methodology (itinerant preaching outside of the word and sacrament ministry of the local church) 2.) emotional manipulation (while Whitefield's orthodoxy is generally acknowledged, his emotionally manipulative homiletical methods are deemed dubious by some). Anyway, I agree that Whitefield is quite the confusing character.
