Centered in the city of Rome, the Church expanded and grew until it became the dominant religion in Europe and beyond. The early growth of the Church had been suppressed by the Romans until the Emperor Constantine became the first to convert the empire to Christianity, and from that point forward, the growth of the Church Was inextricably linked with the Roman Empire, the most powerful military, economic, and political force in the ancient world. For almost 600 years, from the defeat of Carthage in the Second Punic War in 201 BCE to around 395 CE, Rome was one of the most important cities in the world, but things were beginning to change around the time Constantine converted the empire. Rome controlled large areas of the world, but by the 4th century the emphasis had shifted from military conquest to the control of lucrative trade routes. The problem was that the city of Rome, isolated in the southern half of the Italian peninsula, was far from these routes, and this compelled Constantine to establish a major Roman city on the site of ancient Byzantium. The new city, Constantinople, was located on a strategic site controlling the narrow straits between the Black Sea and the Aegean, meaning it was firmly astride some of the most important trade routes in the ancient world between Europe and Asia and between the Mediterranean and the Black Sea. Constantinople became the second most important city of the Roman Empire, thriving in parallel with Rome, but then the empire split into Eastern and Western provinces, with Constantinople the capital of the east and Rome the capital of the west. Control of trade routes made Constantinople increase in power and influence while Rome became less important. However, not all power and influence shifted east, because one important institution remained firmly linked with the city of Rome: the Bishops of the Church. Under the rule of previous emperors, Christian Bishops had not only been formally recognized, but had been given power within the Roman state. The most important of all was "I Sommi Pontefici Romani" the supreme pontiff of Rome. The earliest holders of this title were martyrs and saints of the Church, but by the time of the rise of Constantinople, this role was elected by the other Bishops of the Church. This role would later become known as the Pope (from the Greek word "pappas" meaning "father"), but even before that title was adopted, the Supreme Pontiff in Rome was widely recognized as the leader of the Church. In historical terms, these early leaders of the Church are often referred to as "popes" even though that title was not formally adopted until after the division the Church. Rome's preeminence was not a situation that was welcomed in Constantinople, now the center of the Byzantine Empire and a thriving and wealthy metropolis. After being sacked by outsiders, Rome had become a virtual ghost town, partially ruined and inhabited by a small number of hardy survivors, yet in center of the crumbling city was the Vatican Borgo, the Palace of the Supreme Pontiff and the heart of the Church. In retrospect, it is easy to see that this was a situation that was bound to lead to conflict and disagreement, with the Greek-speaking Eastern Orthodox Church centered in Constantinople and being governed by Latin-speaking popes in a faraway city. Moreover, there had already been theological disputes as far back as Constantine's time, which had led to the famous Council of Nicaea in the 4th century CE. This book chronicles the events that led to the schism, the key figures that played a hand in the confusion, and how the contentious issues were finally resolved.

In the second edition of this major work, Dominican theologian Aidan Nichols provides a systematic account of the origins, development and recent history—now updated—of the relations between Rome and all separated Eastern Christians. By the end of the twentieth century, events in Eastern Europe, notably the conflict between the Orthodox and Uniate Churches in the Ukraine and Rumania, the tension between Rome and the Moscow patriarchate over the re-establishment of a Catholic hierarchy in the Russian Federation, and the civil war in the then federal People’s Republic of Yugoslavia, brought attention to the fragile relations between Catholicism and Orthodoxy, which once had been two parts of a single Communion. At the start of the twenty-first century, in the pontificate of Benedict XVI, a papal visit to Russia—at the symbolic level, a major step forward in the ‘healing of memories’— appears at last a realistic hope. In addition, the schisms separating Rome from the two lesser, but no less interesting, Christian families, the Assyrian (Nestorian) and Oriental Orthodox (Monophysite) Churches, are examined. The book also contains an account of the origins and present condition of the Eastern Catholic Churches—a deeper knowledge of which, by their Western brethren, was called for at the Second Vatican Council as well as by subsequent synods and popes. Providing both historical and theological explanations of these divisions, this illuminating and thought-provoking book chronicles the recent steps taken to mend them in the Ecumenical Movement and offers a realistic assessment of the difficulties (theological and political) which any reunion would experience.

An insider’s account of the Eastern Orthodox Church, from its beginning in the era of Jesus and the Apostles to the modern age In this short, accessible account of the Eastern Orthodox Church, John McGuckin begins by tackling the question “What is the Church?” His answer is a clear, historically and theologically rooted portrait of what the Church is for Orthodox Christianity and how it differs from Western Christians’ expectations. McGuckin explores the lived faith of generations, including sketches of some of the most important theological themes and individual personalities of the ancient and modern Church. He interweaves a personal approach throughout, offering to readers the experience of what it is like to enter an Orthodox church and witness its liturgy. In this astute and insightful book, he grapples with the reasons why many Western historians and societies have overlooked Orthodox Christianity and provides an important introduction to the Orthodox Church and the Eastern Christian World.
