One warm Sunday evening in September 1993, I found myself walking aimlessly around the McMaster University campus. Earlier the same week, I had seen a poster advertising “Church at the John,” an event organized by the McMaster chapter of the Inter-Varsity Christian Fellowship (IVCF). Since I was academically interested in conservative Protestantism, and since at that point I knew no one in the city, I decided, for lack of other options, to attend this meeting. What I found there fell completely outside my expectations, prompted an elaborate series of questions, and ultimately resulted in the present book. Since I assumed that the meeting would be small, I worried that being ten minutes late might draw unwanted attention to my presence. As I descended the stairs of the Downstairs John (or simply “the John”), McMaster’s largest student bar, I could hear the noises of a large group of people. I thought I might have misread the poster a few days earlier; when I entered the bustling room, I was virtually certain I had. Except for the well-lit stage at one end of the room, the John was dark, and almost six hundred people were crowded into a space designed for no more than four hundred and fifty. The room was narrow and long, with a low stage at one end, pool tables at the opposite end, and a bar along the side of the room. People were standing and sitting in the aisles, on the bar, and against the walls beneath the bikini-clad models and slogans that festooned the neon beer signs. I discreetly asked one person who was standing against the wall if this was the right room for the IVCF meeting, and he replied that it was. I looked at him more intently to determine if he was joking, but he just smiled at me politely and bowed his head. After a few confusing moments, I realized he was praying. I turned away from him and noticed that all the other people in the room had bowed their heads in a prayer being led by a demure young woman on the stage.
