I don’t have time now to get in depth, but I wanted to at least give you the link.
9 Marks Ministries‘ March/April e-journal is on the topic of fundamentalism and separation.
Some of the very issues, I’ve been debating about recently here are covered (including article’s I’ve referenced by Albert Mohler and Wayne Grudem). There are other new articles and thoughts on this topic from Ian Murray, Mark Dever and others. And they include David Doran and Mark Minnick with a fundamentalist perspective. Ben Wright, of Paleoevangelical, also contributes.
Again, I’m pressed for time, so I’ll just give you the link to the PDF copy as well as a link to the page that introduces the journal and provides html links to the articles.
