I'm currently studying the open theism issue. The quickest way to get up to speed is from reading and/or listening to debates (preferrably from degreed theologians). I am only aware of a couple of these. One is a book published by Baker Academic called, Does God Have a Future?: On Divine Providence, found here: http://www.spiritrestoration.org/bookreviews/Does_God_have_a_future.htm, which was a collection of email exchanges between Christopher Hall and John Sanders. And the [b][i]Journal of the Evangelical Theological Society[/i][/b] published a few exchanges between John Sanders, Gregory A. Boyd, Clark Pinnock and Bruce A. Ware.
And currently in progress at www.TheologyOnLine.com is a debate between Dr. Samuel Lamerson from D. James Kennedy’s Knox Theological Seminary and the pastor from Denver Bible Church.
Those are the only debates I'm aware of (by degreed theologians) on the topic of open theism. If anyone knows of any others, please post them here. I would greatly appreciate it. Thanks a lot in advance.
James White debated John Sanders a couple of years ago in Florida. Check his website www.aomin.org under the MP3 messages and you should be able to locate it for purchase.
