In order, Judaism: around 2000 BC, Christianity: A.D. 1 century, Catholicism and Orthodox Church: 1054, Protestantism and Christianity:16th century.
For example, it can be said that God was born blessed, but because human ancestors committed crimes, it brought trouble to future generations, and as a result, human beings needed redemption. In order to save people, God first chose a nation, that is, the Israeli nation, and planned to produce a savior in this nation. This nation is the earliest Judaism. In the first century, the savior finally came, and he was Jesus. However, this Jesus is not considered by Jews as the savior promised by God. After Jesus was killed and resurrected, his disciples began to preach his truth and gradually formed Christianity. More than a thousand years later, due to the reasons of the Eastern and Western Roman empires, the political division also led to the gradual division of religion, which eventually split into two parts in 1054. Byzantium in the east formed the present Orthodox Church, and Rome in the west formed the Roman Catholic Church, also known as Roman Catholicism. Later16th century, the church was very corrupt and continued to reform. Martin Lu Deben wanted to reform the church, but it was used by the aristocratic forces at that time, and finally turned into war killings. Later, they gradually formed an anti-religious oath. At the same time, in Britain, because of the divorce and remarriage in Britain, the Catholic church is not allowed to divorce, even the king of England is no exception. In this way, the king of England established another church, called the Allergan Church, and also accepted the reformed ideas from Europe. Because the word "anti-Christianity" was harsh when it was introduced into China, some people translated it as "Christianity" and confused it with Christianity in a broad sense from the beginning. In order to distinguish them, we generally call them Protestantism, or Jesuits, or Protestantism in mainland China.
The main differences between them are as follows: Judaism does not recognize Jesus in Christianity as the savior promised by God, Orthodox does not recognize the Bishop of Rome as the head of the universal church, and Protestantism believes that salvation depends on faith. Therefore, the external organization of the church is unnecessary. Ann Reagan's Anglican Church does not recognize the supremacy of the Pope, who means the head of state.
