The historical development of Christianity, its relationship with social and political phenomena of life, the emergence of various faiths is a very interesting topic for researchers of Christian history. The history of Christianity is difficult to understand properly without having an idea of the various political, economic, social, scientific and aesthetic trends of each era, the life of the Church is correlated here with the corresponding circumstances of secular life. Consideration of historical figures, events, views and currents or movements in the true temporal and geographical setting helps to understand the historical movement of Christianity. Earl Kearns's book is intended for students of theological faculties, as well as for anyone interested in issues of Church history.
