The word first appeared in
Michele Ruggieri's Chinese translation of the
Decalogo, or
Ten Commandments.
Matteo Ricci later wrote a
catechism entitled
Tiānzhŭ Shíyì (天主實義,
The True Meaning of the Lord of Heaven). "
Catholicism" is most commonly rendered as
Tiānzhǔjiào (天主教, "Religion of the Lord of Heaven"). An individual Catholic is
Tiānzhŭjiào tú;
tú includes the meanings "disciple" and "believer." The same
hanja characters are used in the Korean words for Catholicism and Catholic believer. ==See also==
