This article explains how the Episcopalian Diocese of Atlanta planned to vote on whether to exonerate Pelagius and admit his ideas as potentially instructive for the church. The vote was planned for November 4, and I have not heard how it turned out. But considering that they even considered having a referendum, the outlook does not seem good. Apparently old heresies never die, they just hang around for future vindication.
Update: Mark Lydecker sent me this link which says that the Episcopalians defeated the potential return to Pelagius. Orthodoxy has been saved, to fight another day. This reminds me of the great quote that Richard Muller posted on his office door (I forget who it was attributed to): “orthodoxy does not have to defeat heresy, it only has to outlast it.” This has been proved true in the last five years or so in American evangelicalism, and it will prove true yet again.
