Bro Winford Claiborne made some great points about how agnosticism is related to the "Emerging Church" movement at the recent Spiritual Sword lectureship. He almost specifically discussed this idea that nothing can be certain.

Here is a link to his lecture: http://www.getwellchurchofchrist.org/2008video.htm

The discussion is the book of Deuteronomy and Bro. Claiborne discusses how the ideologues of the "ECM" wouldn't like the book too much because Moses used the word "command" more than 70 times and the word "commandment" more than 40 times in the book.

Enjoy the lecture. The link will take you to Getwell Church's SS page.
