Translation guide
The English word 'apostle' primarily refers to the early Christian leaders sent by Jesus, but can also mean a pioneering advocate of a cause. In Japanese, the most common equivalent is 使徒 (shito) for the biblical sense, while 伝道者 (dendōsha) or 唱道者 (shōdōsha) can be used for a passionate advocate.
Referring to one of the twelve original disciples of Jesus, or a prominent early Christian missionary like Paul.
Referring to a person who passionately promotes a cause, idea, or movement; a pioneer or leading figure.
Avoid directly translating 'apostle' as 使徒 when not referring to the biblical context. For a passionate advocate, use 伝道者 or 唱道者 instead. Using 使徒 for a non-religious advocate may sound odd or overly religious.
