In the medieval Christian papacy there was a conflict called "investment struggle" between the emperor and the pope. What is the essence of this conflict between the church and the state? It focuses on the claims of the Universal authority of the Pope and the Pope. Investment is defined as a ritual or action of investing someone in an advanced position or setting up. With this understanding, why does the emperor ask this question, what kind of authority is based on what grounds the Roman bishop has power over all other bishops, even all Christians It is easy to understand.
Beginning with an early Christian, the early medieval Christians inherited a unified church by major beliefs, stable Bible classics and a well-developed philosophical tradition. The history of medieval Christianity dates back to the period after the collapse of the Roman Empire to Medieval Christianity - Protestant Reform. Meanwhile, the institutional structure of Western Christianity was different from that of Christianity in later Middle Ages. Contrary to the later church, the early medieval churches consisted mainly of monasteries. Since Simon's custom made the office of the church the property of the local prince, the monastery was the only church facility independent of the local prince. Furthermore, the Pope is relatively weak, and his power is limited mainly to Central Italy. The religious order has only risen rapidly since the Middle Ages.
Medieval Christianity began. In fact, recent research has suggested that it is difficult to judge where the end of the early Christianity is and that medieval Christianity has evolved over the centuries (Markus 1990) . However, someone has to start from somewhere and provide manageable blocks during the guidance period. And it is easy for students to understand. Still, if the limit set for a particular time period is not completely random, I will explain why some reason for that.
I am working on four periods in Christian division of labor: the early Christianity, the medieval Christian world, modernity, and an unnamed new era that I have always called 'next to happen'. During each period there are several important points: the constitution and Gregory transformation between the early Christianity and medieval Christianity, the transformation between medieval and contemporary Christianity, modern and later Post modern between. . I do not think that I mentioned early Christianity in this blog. In a sense, this is the history of my weakest church. But perhaps more importantly, the early Christianity was somewhat deleted, as this blog is primarily interested in contrasting modern and postmodern.
