"Evangelical" -- What's In a Word?

I realize that the speech I'm linking you to right here (an address by Church of England Archdeacon, the Rev. Dr. Charles D. Alley, given to the Episcopal Evangelical Assembly Conference at Virginia Theological Seminary) is probably for a limited audience. But if you like history and religion, if you would benefit from a discussion of what words like "evangelical" truly mean, if you're interested in the cultural divide between modernists and those who yet adhere to Scripture as a holy and practicable source -- then you'll certainly enjoy this.
