基督教 in Chinese / Japanese...

基督教 is the Chinese, Japanese and Korean word for “Christianity.”

Just as in English, this word is often used to mean “Protestant” but includes Catholics in the true definition.

It is the word used to refer to the whole “Christian religion” or “Christian Faith,” and therefore, it can be translated as “Christianity.” However, used as an adjective in regard to a person, it would translate as “Christian.” But more like saying, “His religion is Christianity,” rather than a noun form.

If you break it apart, the characters mean Base/Foundation Leading/Supervising Religion/Teaching. It makes more sense in Japanese, Chinese, and Korean. The first two characters together are translated as “Christ.” So you can also say this means “Christ's Religion” or “Christ's Teachings” when directly translated, or in reverse, “The Religion of Christ” or “The Teaching of Christ.”

Notes: The last character has a slight difference in one stroke - however, in calligraphic form, this will not be apparent. This entry can easily be read by any Korean person who knows Hanja characters (Chinese characters used in Korean).

基督教徒 is the most verbose (longest) word for “Christian” in the Chinese and Japanese languages.

The literal translation of the first two characters is Christ.
The third Character means “Religion” or “Teaching.”
The last character means “apprentice” or “disciple.”

Altogether these three characters mean “Christ's Teaching Disciple” or “Christ's Religion Apprentice.”

Note: The last two characters are sometimes translated together as “follower (of a religion),” so you could also say it means “Follower of Christ.”

This four-character title makes it very clear what you are talking about in Chinese.
