Philip Schaff

Philip Schaff

Philip Schaff (1819–1893) was one of the most distinguished church historians who ever lived. He was educated at Tübingen, Halle, and Berlin, and was professor of church history and biblical literature at German Reformed Theological Seminary. When the Civil War forced the seminary to close, Schaff moved to Union Theological Seminary. Schaff had an enormous influence on German Reformed churches in America, and he wrote History of the Christian Church, Creeds of Christendom, and The Principal of Protestantism.

Saint Gregory the Great

Saint Gregory the Great (AD 540–AD 604) was born into Roman nobility and was prefect of Rome before converting the family estate into a monastery dedicated to St. Andrew, where he remained until AD 579, when he was appointed as apocrisiarius to Constantinople. He began his papacy in AD 590 under the name Pope Gregory I.

Gregory was a great leader, with successful missionary campaigns that changed the reach of Christianity in Europe. He was also an able reformer, and was known as “the Father of Christian Worship” for his work in developing the liturgy of his day. Upon his death, he was immediately declared a saint by popular acclamation, and is venerated as a saint in the Roman Catholic, Eastern Orthodox, Anglican and some Lutheran churches. Much of Gregory’s abundant work has survived, including Morals on the Book of Job and Dialogues.
