in this book I have not hesitated to raise again some of the old differences (over baptism, the Lord’s Supper, church government, the millennium and the tribulation, and predestination, for example) in the hope that, in some cases at least, a fresh look at Scripture may provoke a new examination of these doctrines and may perhaps prompt some movement not just toward greater understanding and tolerance of other viewpoints, but even toward greater doctrinal consensus
