天主教
Tiān zhǔ jiào · HSK 7
Catholicism
✝️ 天主教 = heaven + lord + teaching: the religion of the Lord of Heaven
天主 (heaven-lord) is the specific Chinese name Catholic missionaries chose for God, so 天主教 literally reads as the teaching of the Heavenly Lord. The 教 ending marks an organized religion, the same character used in 佛教 Buddhism and 道教 Daoism.
天 — 一 (one/sky) above 大 (big person)
Originally a pictograph of a person (大) with an emphasized head, representing what is above — the sky or heavens. The top stroke evolved into 一, symbolizing the vast expanse overhead. From 'sky' it extended to mean 'day,' 'heaven,' and 'nature.'
主 — flame/lamp on top of a stand 王
Originally a pictograph of a lamp with a flame on top of its stand, representing the lord or master of the household who tended the fire. The meaning extended from 'lamp/host' to 'master, owner, main, principal'. The character 炷 (wick) preserves the original 'lamp' sense.
教 — 老 (filial son being taught) + 攵 (hand with stick)
教 originally depicted an adult holding a stick or rod (攵) instructing a child, often shown with the element 爻 (lessons/counting) above 子 (child). It is a classic associative compound meaning 'to teach' or 'to instruct,' with the right side suggesting discipline and guidance. The modern meanings 'teach, religion, doctrine' all extend from this image of formal instruction.
