My brothers and sisters, if anyone among you wanders from the truth and someone turns him back, he should know that the one who turns a sinner back from his wandering path will save that person’s soul from death and will cover a multitude of sins (James 5:19-20, NET).
I recently came across the following commentary from Charles Haddon Spurgeon, the pastor of New Park Street Chapel (the Metropolitan Tabernacle) in London for 38 years. Five years before he passed away, he ignited a controversy among the Baptists from an article he wrote about what he termed the “Downgrade Controversy.” Because of issues surrounding this, his church became disaffiliated with the Baptist Union. This wikipedia article describes:
Contextually the Downgrade Controversy was British Baptists’ equivalent of hermeneutic tensions which were starting to sunder Protestant fellowships in general. The Controversy took its name from Spurgeon’s use of the term “Downgrade” to describe certain other Baptists’ outlook toward the Bible (i.e., they had “downgraded” the Bible and the principle of sola scriptura). Spurgeon alleged that an incremental creeping of the Graf-Wellhausen hypothesis, Charles Darwin’s theory of evolution by natural selection, and other concepts was weakening the Baptist Union and reciprocally explaining the success of his own evangelistic efforts.
I found the following commentary by Spurgeon on James 5:19-20 to be applicable to the discussion around fundamentals of the Christian faith in the context of the discussions often occuring in Emergent/ing circles. I am interested in hearing your feedback on Spurgeon’s comments and the scripture from James that he is commenting on. If you don’t agree with him, how would you understand James’ intended meaning?
It was not merely that he fell into a mistake upon some lesser matter which might be compared to the fringe of the gospel, but he erred in some vital doctrine&emdash;he departed from the faith in its fundamentals. There are some truths which must be believed, they are essential to salvation, and if not heartily accepted the soul will be ruined. This man had been professedly orthodox, but he turned aside from the truth on an essential point.

I came across a review of “Velvet Elvis” by Rob Bell done by Greg Gilbert of 9Marks.org 
Dan Kimball has coined the term “Vintage Faith” to describe the new Emergent style churches. From his website
