There is a theological debate simmering in the blogosphere about Calvinists and Calvinism. Debate is a good thing. It can help bring us to consensus, and that would be good for Christianity.
Let’s start with the definitions: Spurgeon’s Exposition of the Doctrines of Grace; Arminianism from the Elwell Evangelical Dictionary, and Calvinism, Arminianism and the Word of God by Chuck Smith of Calvary Chapel.
On the Reformed side of the debate, visit: Adrian Warnack: Calling All Arminian Prayers; Alpha and Omega Ministries: HyperCalvinism; The JollyBlogger: In Defense of Internet Calvinists; The Irvins: The Flaw in Evangelism (Broken link, active June 15, 2005), For Whom Did Christ Die; Is Calvinism Inconsistent (Broken link, active June 15, 2005); Can Calvinism Be Taught, and many others (browse around).
On the other side of the debate, visit: The Internet Monk: Why I’m Not Like You; Ilona at True Grit: Implications (Broken link, active June 15, 2005), and also Covenants and Counterpoints, and more (browse around); The Bible Archive: Rockin’ With Russ (a collection of articles on each of the five points of Calvinism) (Broken link, active June 15, 2005).
These essays are just a start. Following the links on these pages and looking around a bit will take you to more. I should put the obligatory disclaimer in here: linking to these essays does not indicate my agreement with them. I am researching the debate as well. I am posting the links as a service for others who have questions (or answers) and who would like to follow the debate.
Any of these essays would make good practice material for your rhetoric stage student. Identify and research the points made, identify the logic and the use of Scripture, and support or refute the claims.
Update: Thanks to Jen for recommending Debating Calvinism in the comments. Thanks to Kim for recommending PyroManiac’s overview of the Internet debate in Quick and Dirty Calvinism. (Please post in the comments if anyone has more great recommendations.)
