 Ricci's translation also invited the displeasure of Dominicans and that of the Roman Curia; On March 19, 1715, Pope Clement XI released the Edict "Ex Illa Die", stating that Catholics must use "Tianzhu" instead of "Shangdi" for Christianity's God.When Protestantism entered China in the mid of 19th century, the Protestant missionaries also encountered a similar issue; some preferred the term "Shangdi", while some preferred the term "Shen" (god).A conference held in 1877 in Shanghai, discussing the translation issue, also believed that "Shangdi" of Confucianism and the Christian concept of God are different in nature.
