ABSTRACT
This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book discusses the problem of interreligious relations appears in different contexts based on two geographical areas of western Eurasia. It addresses that of confessional divisions and interfaith dialogues in Western Christendom considered in terms of Catholic-Protestant, as well as Protestant denominational divisions. The book essentially covers the early modern era with some prolongation into the nineteenth century. It discusses "religious pluralism" in the vast space extending around the Mediterranean, from the Iberian Peninsula to western Asia. Forms of coexistence may vary according to the religious identity defined by each confessional group for itself. This is true for people living abroad, thus obliged to adapt themselves to a foreign environment with a different religious institution. The book analyzes the process by which Greek Catholics tried to establish their identity in complex political and religious circumstances.
