Following are a number of back-translations of Romans 15:3:
Uma: “For Kristus also did not seek his own happiness, he was ready to undergo suffering in his following God. In the Holy Book long ago there are words that foretell the Lord Yesus that say: ‘All their words disparaging God have struck/hit me.'” (Source: Uma Back Translation)
Yakan: “Because Isa Almasi he did not please himself but he yielded/surrendered to be criticized/to-be-put-down. It was written about this in the holy-book, saying, ‘The evil words spoken by people to you, God, hit me.'” (Source: Yakan Back Translation)
Western Bukidnon Manobo: “For as for Christ, he did not think about what He wanted. For a prophecy was written long ago which is His words to God in which He says, ‘The evil words of people who insulted you, this was also an insult to me,’ which is to say, if He obeyed His own desires, then people would not have insulted Him.” (Source: Western Bukidnon Manobo Back Translation)
Kankanaey: “Because even Cristo, it was not what pleased himself that he thought about, because there is a written word of God concerning him which says, ‘The people’s despising of you (sing.), God, I am the one who was despised.'” (Source: Kankanaey Back Translation)
Tenango Otomi: “Because Christ didn’t look for just his own good. The Holy Book says what word he told God. He said: ‘The people who speak against you also speak against me.’ he said.” (Source: Tenango Otomi Back Translation)
The Greek Christos (Χρηστός) is typically transliterated when it appears together with Iésous (Ἰησοῦς) (Jesus). In English the transliteration is the Anglicized “Christ,” whereas in many other languages it is based on the Greek or Latin as “Kristus,” “Cristo,” or similar.
When used as a descriptive term in the New Testament — as it’s typically done in the gospels (with the possible exceptions of for instance John 1:17 and 17:3) — Christos is seen as the Greek translation of the Hebrew mashiaḥ (המשיח) (“anointed”). Accordingly, a transliteration of mashiaḥ is used, either as “Messiah” or based on the Greek or Latin as a form of “Messias.”
This transliteration is also used in the two instances where the Greek term Μεσσίας (Messias) is used in John 1:41 and 4:25.
In some languages and some translations, the term “Messiah” is supplemented with an explanation. Such as in the GermanGute Nachricht with “the Messiah, the promised savior” (Wir haben den Messias gefunden, den versprochenen Retter) or in Muna with “Messiah, the Saving King” (Mesias, Omputo Fosalamatino) (source: René van den Berg).
In predominantly Muslim areas or for Bible translations for a Muslim target group, Christos is usually transliterated from the Arabic al-Masih (ٱلْمَسِيحِ) — “Messiah.” In most cases, this practice corresponds with languages that also use a form of the Arabic Isa (عيسى) for Jesus (see Jesus). There are some exceptions, though, including modern translations in Arabic which use Yasua (يَسُوعَ) (coming from the Aramaic Yēšūa’) alongside a transliteration of al-Masih, Hausa which uses Yesu but Almahisu, and some Fula languages (Adamawa Fulfulde, Nigerian Fulfulde, and Central-Eastern Niger Fulfulde) which also use a form of Iésous (Yeesu) but Almasiihu (or Almasiifu) for Christos.
Other solutions that are used by a number of languages include these:
Dobel: “The important one that God had appointed to come” (source: Jock Hughes)
Nyongar: Keny Mammarap or “The One Man” (source: Warda-Kwabba Luke-Ang)
Mairasi: “King of not dying for life all mashed out infinitely” (for “mashed out,” see salvation; source: Lloyd Peckham)
Binumarien: Anutuna: originally a term that was used for a man that was blessed by elders for a task by the laying on of hands (source: Desmond Oatridges, Holzhausen 1991, p. 49f.)
Nyongar: Keny Boolanga-Yira Waangki-Koorliny: “One God is Sending” (source: Warda-Kwabba Luke-Ang)
Uab Meto: Neno Anan: “Son of heaven” P. Middelkoop explains: “The idea of heavenly power bestowed on a Timorese king is rendered in the title Neno Anan. It is based on the historical fact that chiefs in general came from overseas and they who come thence are believed to have come down from heaven, from the land beyond the sea, that means the sphere of God and the ghosts of the dead. The symbolical act of anointing has been made subservient to the revelation of an eternal truth and when the term Neno Anan is used as a translation thereof, it also is made subservient to a new revelation of God in Jesus Christ. The very fact that Jesus came from heaven makes this translation hit the mark.” (source. P. Middelkoop in The Bible Translator 1953, p. 183ff. )
Law (2013, p. 97) writes about how the Ancient GreekSeptuagint‘s translation of the Hebrew mashiah was used by the New Testament writers as a bridge between the Old and New Testaments (click or tap here to read more):
“Another important word in the New Testament that comes from the Septuagint is christos, ‘Christ.’ Christ is not part of the name of the man from Nazareth, as if ‘the Christs’ were written above the door of his family home. Rather, ‘Christ’ is an explicitly messianic title used by the writers of the New Testament who have learned this word from the Septuagint’s translation of the Hebrew mashiach, ‘anointed,’ which itself is often rendered in English as ‘Messiah.’ To be sure, one detects a messianic intent on the part of the Septuagint translator in some places. Amos 4:13 may have been one of these. In the Hebrew Bible, God ‘reveals his thoughts to mortals,’ but the Septuagint has ‘announcing his anointed to humans.’ A fine distinction must be made, however, between theology that was intended by the Septuagint translators and that developed by later Christian writers. In Amos 4:13 it is merely possible we have a messianic reading, but it is unquestionably the case that the New Testament writers exploit the Septuagint’s use of christos, in Amos and elsewhere, to messianic ends.”
