Catholicism is also known as the "Catholic Church","Roman Catholic Church","Catric Church", and is sometimes called the "Old Church" to distinguish it from Protestantism. Together with Orthodoxy and Protestantism, they are called the three major Christian sects. Christianity was officially divided into Eastern and Western factions in 1054. The Eastern Faction calls itself "Orthodox Church, which is mainly a Greek-speaking area, with Constantinople as the center and is the Orthodox Church. The Western faction calls itself "Catholic Church" mainly popular in Latin speaking areas, centered on Rome and is Catholic. The Catholic Church believes in the Lord God and Jesus Christ, and honors Mary as the Virgin Mary. In the first year of Yongzheng of the Qing Dynasty (1723), a ban was issued. After the Opium War, Catholic missionaries gained the right to preach freely in China in accordance with the provisions of the China-France Huangpu Treaty. On November 11, the Qing government announced a ban on the five ports. On February 8, 1846, under repeated pressure from the law envoys, the Qing Dynasty issued another decree to lift the ban on Catholicism across the country and restore the church during the Kangxi period. Since then, Western missionaries have increasingly poured into China. In 1870, 250 Catholic (Jesuit) missionaries came to China, and by 1874, 436 Christian (Protestant) missionaries came to China.
