Shang-ti in later times was often referred to, in abbreviation, as Ti (Lord). But Ti was also commonly used in later history to refer to an emperor; his origin is divine because his First Ancestor is Shang-ti. Christian missionaries adopted Shang-ti as the name of God, though Tʾien-chu (Lord of Heaven) was also used.
