This is a monumental work of theology. Written just after the sacking of Rome, it starts by answering how God could allow a Christian city to fall. This proceeds with a detailed attack on paganism, and a defense of Christianity. He belabors these points, but then goes on to a treatise on Christian theology which sets a decided uncompromising tone. He endorses the predestination arguments later made by Calvin, and shows a narrow moral view. What you get is an excellent view of the early Christian Church, a church and time very different from today.
