I recently taught a group of Chicago church leaders on missional-ecumenism. If you would like to watch this presentation it lasts a little over an hour and a half. (I believe it is 94 minutes long.) I offer it to readers of this blog who have the time and interest in watching and hearing my message on mission and unity in a very human and interactive context.
