The Greek that is often translated as “church” in English is translated into Avaric as imanl’urazul ahlu: “the community of believers” or “the believing people.” Magomed-Kamil Gimbatov and Yakov Testelets (in The Bible Translator 1996, p. 434ff.) talk about the genesis of this term:
“The word ‘Church’ presents particular difficulties, as we might expect when we think that even many Christians do not understand it correctly. When people today say ‘church,’ they often mean a particular building, or an organization consisting chiefly of clergy (priests and monks). It is even harder to find a word or combination of words which adequately translates the meaning for people unfamiliar with Christianity. Surprisingly, the Greek word ekklesia, indicating in the classical language ‘an assembly of the people,’ ‘a gathering of citizens,’ has come into Avar and other Dagestani languages in the form kilisa. This, like the word qanch (‘cross’), is an ancient borrowing, presumably from the time before the arrival of Islam, when Dagestan came under the influence of neighboring Christian states. In modern usage, however, this word indicates a place of Christian worship. Thus it is completely inappropriate as a translation of its New Testament ancestor ekklesia.
“We were obliged to look at various words which are closer to the meaning of the Greek. Some of these words are dandel’i (‘meeting’), danderussin (‘assembly’), the Arabic-derived mazhlis (‘meeting, conference’), zhama’at (‘society, community’), ahlu (‘race, people, family, group of people united by a common goal or interest’, as in the Arabic phrase ahlu-l-kitab ‘people of the Book’ or ‘people of the Scriptures’), which describes both Jews and Christians, and ummat (‘people, tribe’). In Islamic theology the phrase ‘Mohammed’s ummat’ means the universal community of Muslims, the Muslim world, in the same way as the Christian world is known as ‘Isa’s ummat.’ None of these descriptions on their own, without explanation, can be used to translate the word ‘Church’ in the New Testament. Thus, after long consideration, we adopted the phrase imanl’urazul ahlu, meaning ‘the community of believers,’ ‘the believing people,’ This translation corresponds closely to New Testament teaching about the Church.
“It is interesting that the same word ahlu with the meaning ‘tribe, community’ has been used by translators for different reasons in the introduction to the Gospel of Luke in order to translate the expression in the original Greek pepleroforemenon en hemin pragmaton (πεπληροφορημένων ἐν ἡμῖν πραγμάτων), which the Russian Synodal translation renders ‘about the events well-known amongst us’ (Luke 1:1). The expression ‘amongst us’ cannot be translated literally into Avar, but has to be rendered ‘among our people’; and here the same term was used as for the word ‘church’, literally ‘among our tribe, community (ahlu).'”
In Kamo “church” is fang-balla (“owners of writing-people”) when referring to the church community and “house of writing-people” when referring to a church building. David Frank explains: “In Kamo culture, Christianity was associated with writing, so Christianity is called balla, which they say means ‘people who write.’ Christianity is balla, and Christians are called fang-balla, which means ‘owners of Christianity.’ That is the term that is used for the church, in the sense of people, rather than a building. In Philemon 1:1b-2a, Paul says he is writing ‘To our friend and fellow worker Philemon, and to the church (fang-balla ‘owners of Christianity) that meet in your house.’ The word fang “owner’ is very productive in the Kamo language. A disciple is an ‘owner of learning,’ an apostle is an ‘owner of sending,’ a believer is an ‘owner of truth,’ a hypocrite is an ‘owner of seeing eyes.’ The expression ‘house of writing-people’ is used in Matthew 16:18, which reads in Kamo, ‘And so I tell you Peter, you are a rock, and on top of this rock foundation I will build my house of writing-people, and never even death will not be able to overcome it.” (See also Peter – rock)
In Bacama there also is a differentiation between the building (vɨnə hiutə: “house of prayer”) and the community (ji-kottə: “followers”) (source: David Frank in this blog post).
In 16th-century Classical Nahuatl, a transliteration from Spanish (Santa Yglesia or Santa Iglesia) is typically used rather than a translation, making the concept take on a personified meaning. Ottman (p. 169) explains: “The church building, or more precisely the church complex with its associated patio, has a Nahuatl name in common usage — generally teopan, something like ‘god-place,’ in contradistinction to teocalli, ‘god-house,’ applied to a prehispanic temple — but the abstract sense is always Santa Iglesia, a Spanish proper name like ‘Dios’ or ‘Santa María’, and like ‘Santa María’ often called ‘our mother.’ As a personified ‘mother,’ in the European tradition as well as in Nahuatl, She instructs Her children or chastises them; as Bride of Christ, She both longs for Her heavenly rest and bears witness to it, in the ‘always-already’ of eschatological time; as successor to the Synagogue, the blindfolded, broken-sceptred elder sister who accompanies Her in painting and sculpture, She represents the triumphant rule of truth. ‘The Church’ can mean the clerical hierarchy; it can also, or simultaneously, mean the assembly of the faithful. It dispenses grace to its members, living and dead, yet it is also enriched by them, living and dead, existing not only on earth but in purgatory and in heaven.”
In Lisu the building (“church”) is called “house of prayer” (source: Arrington 2020, p. 196) and in Highland Totonac the community is referred as “those who gather together” (source: Hermann Aschmann in The Bible Translator 1950, p. 171ff.).
