History of the Christian Church, Volume III: Nicene and Post-Nicene Christianity. A.D. 311-600

In preparing this part of my Church History for the press, I have been deprived of the stimulus of an active professorship, and been much interrupted in consequence of other labors, a visit to Europe, and the loss of a part of the manuscript, which had to be rewritten. But, on the other hand, I have had the great advantage of constant and free access to several of the best libraries of the country. Especially am I indebted to the Astor Library, and the Union Theological Seminary Library of New York, which are provided with complete sets of the Greek and Latin fathers, and nearly all other important sources of the history of the first six centuries
