‘弥撒’ is a loanword from Latin ‘missa’, referring specifically to the central liturgical service of the Catholic Church, commonly translated as ‘Mass’. Though the characters 弥 (mí) and 撒 (sā) individually mean ‘to fill, pervade’ and ‘to scatter, spread’, respectively, their combination here is purely phonetic — they do not convey meaning through semantics but approximate the sound of the foreign term. This is typical of transliterated religious vocabulary in Chinese, where character choice prioritizes pronunciation over literal sense.

The word is used almost exclusively in Christian contexts — especially Catholic ones — and appears in formal, written, or institutional settings such as church announcements, religious education, or interfaith dialogue. It is not used for Protestant worship services (which are typically called ‘礼拜’ lǐbài), nor for non-Christian rituals. While understood by many educated Chinese speakers due to cultural exposure, it remains a specialized term outside religious communities.
