Robert Sungenis will be debated James White in the issue of Calvinism.

This should be a decent debate although White usually doesn't fair that well with Sungenis on the issue of justification.
Since Calvinism is such a radical departure from the New Testament and Robert Sungenis was previously a Calvinist who graduated from Westiminster Seminary this should be good. The bad thing is that James White usually resorts to ad-hominem which ends up making the debate a joke.
