The Greek that is translated in English as “brother” (in the sense of a fellow believer), is translated with a specifically coined word in Kachin: “There are two terms for brother in Kachin. One is used to refer to a Christian brother. This term combines ‘older and younger brother.’ The other term is used specifically for addressing siblings. When one uses this term, one must specify if the older or younger person is involved. A parallel system exists for ‘sister’ as well. In [these verses], the term for ‘a Christian brother’ is used.” (Source: Gam Seng Shae)
In Martu Wangka it is translated as “relative” (this is also the term that is used for “follower.”) (Source: Carl Gross)
