East and West: The Making of a Rift in the Church - Chadwick, Henry (Emeritus Regius Professor of Divinity, University of Cambridge)

This title provides an account of the emergence of divisions between Rome and Constantinople. Starting with the roots of the divergence in Apostolic times, it takes the story to the Council of Florence in the fifteenth century.
