Christianity is a religion based on the life and teachings of Jesus Christ. Most Christian believers, called Christians, are among the three major groups of Roman Catholic, Protestant, or Orthodox. These groups have different beliefs about Jesus and his teachings. But everyone believes that Jesus is the heart of their religion. Most Christians believe that God sent Jesus to the world as a Savior. Christianity teaches that people can receive salvation through Jesus. Jesus lived in a Middle Eastern Jew who was governed by the Romans (later known as Palestine).
Christianity: The reason that the West is Christian is because the Romans used Christianity as a religion of their country. Before the rule of Konstantin I, Christians accounted for only 10% of the Roman population. Konstantin legalized Christianity, and Theodosius I used it as an official religion of the Empire. The doctrine of Christianity was also enacted by the Roman Emperor 's Diet. If there is no support from Roman emperor, it is doubtful whether Christianity has such influence. Expansion: Romans were able to unify Europe, most West Asia and North Africa. They beat Celtic tribes, Carthage, Hellenistic empire and many other countries. This is achieved through their military superiority and their success in the utilization of human resources. The Roman Corps is still considered one of the most successful military in history.
Between the 1 st century and the 4 th century, Christianity gradually became the mainstream religion of Rome. How to deal with the burden of this new religion is the Roman government's top priority. Many Roman kings and emperors responded to Christianity in various ways. In the meantime, Christianity suffered for the soul and soul of the Romans. Through Christian 's first widespread persecution by Christians in December 250, Constantine changed Emperor into Christianity, and Christianity was at the forefront of a matter of time.
