What don't Christians believe? Is Jesus really divine? Is Jesus really human? Can God suffer? Can people be saved by their own efforts?The early church puzzled over these questions, ruling in some beliefs and ruling out others. Heresies and How to Avoid Them explains the principal ancient heresies and shows why contemporary Christians still need to know about them. These famous detours in Christian believing seemed plausible and attractive to many people in the past, and most can still be found in modern-day guises. By learning what it is that Christians don't believe--and why--believers today can gain a deeper, truer understanding of their faith."This is a deeply refreshing book, full of exciting ideas. It manages both to be generous to the heretics and to show the beauty of orthodoxy. It is theologically profound while being immensely readable."--Timothy Radcliffe, former Master of the Order of Preachers (the Dominicans)"This is broadband, big-picture theology, brightly clear and easy to read--not in the least bit 'dogmatic' in the contemporary, negative sense of that word."--The Very Rev Dr Paul Zahl, former rector, All Saints Church, Maryland; former president and dean, Trinity Episcopal School for Ministry, Pennsylvania
