基督教是在巴勒斯坦创立,在罗马帝国发展起来的。随着东西罗马帝国的分裂,基督教会于1054年分为两个教派。以罗马主教为中心的一派自称“公教”,因《史记》上有“天主”一词,我国译为“天主教”。以君士坦丁堡主教为首的一支,自称为“正教”,我国译为“东正教”。1517年宗教改革后新起的新教,原名“抗议教”,天主教称其为“誓反教”,其中国信徒自称为“更正教”,俗称为基督教或耶苏教。译名的不统一,造成三派名称的混乱。今为行文方便计,称罗马教派为天主教,译君士坦丁堡派为东正 Christianity was founded in Palestine and developed in the Roman Empire. With the division of the Eastern Roman Empire, the Christian Church was divided into two denominations in 1054. The faction centered on the Roman bishop claimed to be “Catholic” because of the word “God” in the “Records of the Historian” and our country as “Catholic.” One headed by the bishop of Constantinople, claiming to be “Orthodox”, our country translated as “Orthodox Church.” Protestantism, a Protestant protest after its 1517 Reformation, was originally called Protestantism. Catholics called it “Opposition Protestantism.” Its Chinese believers claim to be “Protestant”, commonly known as Christianity or Jesuits. The unification of translated names has caused confusion in the names of the three factions. This is a convenient text for the time being, saying that the Roman sect is Catholic and that Constantinople is sent to be Tung Ching
