Russell Moore considers why nondenominational churches are the fastest growing in the country:
Are we witnessing the death of America’s Christian denominations? Studies conducted by secular and Christian organizations indicate that we are. Fewer and fewer American Christians, especially Protestants, strongly identify with a particular religious communion—Methodist, Baptist, Presbyterian, Pentecostal, etc. According to the Baylor Survey on Religion, nondenominational churches now represent the second largest group of Protestant churches in America, and they are also the fastest growing.
