NPNF1-03. On the Holy Trinity; Doctrinal Treatises; Moral Treatises

Philip Schaff (1819–1893) was a Swiss-born church historian who taught at Mercersburg and later at Union Theological Seminary in New York. A bridge between German scholarship and the English-speaking church, he founded the American Society of Church History and edited vast reference works. Our library's Nicene and Post-Nicene Fathers series — which he conceived and edited — together with his History of the Christian Church and Creeds of Christendom, came largely through his labors.
