A Source Book for Ancient Church History
by Joseph Cullen Ayer
About the author
Born in Massachusetts in 1866, Joseph Cullen Ayer Jr. became an Episcopal minister, theologian, and church historian. Records of the Ayer family papers describe him as an Episcopal minister and professor of theology, and other library and book records connect him with the Philadelphia Divinity School and with his long scholarly career.
He is chiefly remembered for A Source Book for Ancient Church History (1913), a substantial collection of documents covering Christianity from the apostolic era through the conciliar period. The book’s lasting reputation comes from its practical value: instead of only summarizing events, it gathered important texts in one place for students and general readers interested in how early Christian history was formed.
Available biographical references also indicate that he studied at Harvard and in Germany, earned a doctorate at Leipzig, and served both in Massachusetts and Philadelphia as a clergyman as well as a teacher. Reliable portrait images were not clearly available from the sources I could confirm, so no profile image is included here.
