"Church History, Volume 3 (of 3)" by J. H. Kurtz is a historical account written in the late 19th century. This volume examines church history primarily during the seventeenth century, delving into the relationships between various Christian denominations, the dynamics within the Roman Catholic Church, and the developments within Protestant movements. The opening of this volume lays the groundwork for a detailed exploration of the complexities surrounding different church relationships in the seventeenth century. It begins by highlighting the transient successes and ambitions of the Roman Catholic Church in the East, particularly with the Jesuit missions among the Abysinnains and their attempts to reclaim authority over the Eastern Orthodox Churches. The text then transitions into discussions of Protestantism and Catholicism, noting conversions of Protestant princes, the influence of events like the Revocation of the Edict of Nantes on the Huguenots in France, and the persistent struggles of religious unity and division exemplified through various union attempts and conflicts.
