The work is concentrated at the life and activity of Aurelius Augustine, since his conversion to Christianity; it is obvious from the structure of the book. The author interprets the activity of Augustine as a bishop, his opposing paganism, and his theological treatises. He describes the evolution of Augustine’s ideas, including his doctrine of the state.

In the centre of attention, there is the main work by Augustine, De Civitate Dеi, written in the context of the fall of the Roman Empire. The author compares the theocratic model, presented in the treatise, and the theocratic system of the Papacy in the Middle Ages. At that, G. noted that for the image of the Kingdom of God was not only a certain waymark for Augustine, but also a life guidance, where the main role belonged to the Christian Church.

As for the approach of Augustine to the family and the property, the author stressed some contradictions in the views of Augustine at those two issues. Describing his activity as a bishop, G. noted that it was not limited with the frames of his eparchy, because he was one of the chief opponents in the struggle against Donatism, wide-spread in Africa. Augustine seriously criticized Donatism, because — according G. — he was ardent follower of the idea of the unified Church, and Donatists weakened it.

The author tried to show the views of Augustine in their vastness, including his ideas of the State and the Church, and his philosophy of history. Studying the works by Augustine was important for G., not only in the context of the history of Christianity in the early medieval period; his analysis of the inner evolution of Augustine gave a chance to understand more about the ‘origin of religion in the human soul’. According G., the main event, the turning point in the life of Augustone was his conversion.
