As we all know, Christianity is divided into three systems: Catholicism, Orthodox Church and Protestantism. At the very beginning, Christianity was not divided into sects. The reason later formed a situation of tripartite confrontation split two, mainly results. Among them, the split between Catholicism and Protestantism is mostly understood by Chinese readers when they read history textbooks. For the first time, that is, the breakup between Catholicism and orthodoxy. Let's talk about this section of this section. The official split between Catholicism and Orthodox Church took place in 1054, but the differences between the two sides were formed in the late Rome empire. The separation of God and East orthodox two religion is directly related to the split of Rome empire. In 395 ad, the Empire of Rome was officially divided into the western Rome Empire centered on Italy and the eastern Rome Empire centered on Constantinople. Rome's split is directly related to its geographical structure. The territory of the Rome Empire covers the whole of the Mediterranean, with a relatively loose geopolitical structure and strong independence of the plates, and the limited geographical strength of the traditional Italy is not sufficient to maintain effective control of the plates. In this case, in order to maintain the control of the vast empire of the Empire, Rome can only be divided into two parts in politics. And this political split has also spread to the ideological field. As for the East Rome Empire, with Constantinople as the core, its development, naturally, will show its native color, with more Balkans, Greek civilization, and this localization is further exacerbated by the destruction of Western Rome. In the west, after the destruction of West Rome, the barbarians who took over the territory of West Rome continued to follow the influence of traditional Rome civilization and gradually became Latin. Of course, whether the Hellenistic East Rome or the Latino barbarians, the two are in the European civilization circle, the race and the cultural heritage are all the same, so the two still retain the Christian religion. But the difference between the independence of the geopolitical pattern, politics and the secondary humanity (nationality, language and custom) makes the two inescapable there exist internal antagonism and conflict in the big framework of Christianity. But at the beginning, the antagonism and conflict were not so obvious. In the early Middle Ages, though the Church of Rome also had considerable strength, its status in general was still inferior to that of Constantin Bo F S. This is a good understanding. The subversion of Western Rome, causing the local civilization backwards. And because of the numerous tribes of the barbarians, after the elimination of Western Rome, it has not been able to establish a similar size of the grand Empire, but a split, this political division and the killing of each other, greatly weakened the strength of the original West Rome layout. East Rome has withstood the pressure, because the barbarians, not backward civilization development. In addition, the East Rome still maintained a unified political system. Constantinople had sufficient control over most of the Empire's territory. The Western civilization recession and political chaos, the continued development of civilization and the unification of the two rivers, which is better at a glance. Based on this pattern, even the power of East Rome is not enough to destroy the barbarians in the West and remake the glory of the Rome empire in politics, but at least the status and influence of the Constantinople's universal church is higher than the Rome Vatican at least in the spiritual field. But in the middle middle ages, the situation changed: on the one hand, with the rise of Islam in the Middle East, the East Rome empire was under increasing pressure in the East, and large areas of Asia and North Africa were taken away by Islam; on the other hand, with the growth of the population and the progress of production technology, the development of Western Europe and central Europe was increased and the strength was stronger and stronger - these plates were far from the king. Constantinople, has always been the Church of Rome's sphere of influence. The eastern Rome empire was declining and the Rome patican area became stronger and stronger; the change of the pattern not only severely weakened the political influence of East Rome on the Western Christian world, but also changed the position of the Holy See and the Constantin Bo F S church, which eventually led to the great division of the Eastern and Western churches in 1054, and the emperor Constantinople and the Pope of Rome dismissal each other. Christianity is officially divided into two main religions: the Orthodox Church and the Catholic Church. The two major sects split up and developed independently and continued to fight. But the two faces are very different. The enemy of the Catholic world is mainly from a direction in the East, while the Eastern Orthodox Church and the eastern Rome Empire, in view of the two sides of the Islamic world and the Western Catholic world, are pressed on both sides, and the strategic security situation is obviously poor. Between two fires, the Orthodox Church and the East Rome Empire better and more. By 1453, the Turkey empire of ostan eliminated the Empire of East Rome and occupied Constantinople in one fell swoop. The eastern Rome empire is the main political support of the Eastern Orthodox Church, and the Eastern Orthodox pastoral areas are also mostly in the East Rome version. With the collapse of East Rome, the Eastern Orthodox Church has also suffered a disaster. Although Turkey did not directly eradicate the Orthodox Church, its discriminatory religious policies (such as non Muslims should pay more taxes) led to a large number of Eastern Orthodox believers in the east of the East Rome, and the Orthodox Church suddenly fell to its knees. If history keeps pace with this thread, the Orthodox Church will not be completely destroyed.(in South Eastern Europe, especially in the Balkans, such as Greece, the Orthodox Church remains quite influential), but without strong political support and the loss of the vast majority of pastoral areas and believers, they are not qualified to sit down with the Catholic Church. But that's not the case. Today's Orthodox Church is still in line with Protestantism and Catholicism, and is the three largest Christian religion.
