Acting on a tip and noting his picture missing from the conference line up, I asked the Gateway Church conference organizers if Mark Driscoll would be speaking at their annual conference as planned. On the 13th, conference coordinator Troy Wilcox answered:
That is a great question, as it is a very recent change. Mark Driscoll has been scheduled to speak at the conference for about 6 months, but due to some recent complications he and his ministry are experiencing, he will no longer be able to be the closing speaker. We are hoping to still have him there in some capacity, but that is all pending. I apologize for the late change, and I understand you (sic) disappointment, but it was definitely not intentional. Let me know if you have any other questions. Thanks, Troy Wilcox, Gateway Conference Coordinator
Oh, the disappointment. Gateway Church is where James Robison is an apostolic elder and is another multi-site church which started in a living room.
