Redemptoris Missio §53

⁵³ Missionaries, who come from other churches and countries, must immerse themselves in the cultural milieu of those to whom they are sent, moving beyond their own cultural limitations. Hence they must learn the language of the place in which they work, become familiar with the most important expressions of the local culture, and discover its values through direct experience. Only if they have this kind of awareness will they be able to bring to people the knowledge of the hidden mystery (cf. Rom 16:25-27; Eph 3:5) in a credible and fruitful way. It is not of course a matter of missionaries renouncing their own cultural identity, but of understanding, appreciating, fostering and evangelizing the culture of the environment in which they are working, and therefore of equipping themselves to communicate effectively with it, adopting a manner of living which is a sign of gospel witness and of solidarity with the people. Developing ecclesial communities, inspired by the Gospel, will gradually be able to express their Christian experience in original ways and forms that are consonant with their own cultural traditions, provided that those traditions are in harmony with the objective requirements of the faith itself. To this end, especially in the more delicate areas of inculturation, particular churches of the same region should work in communion with each other and with the whole Church, convinced that only through attention both to the universal Church and to the particular churches will they be capable of translating the treasure of faith into a legitimate variety of expressions. Groups which have been evangelized will thus provide the elements for a "translation" of the gospel message, keeping in mind the positive elements acquired down the centuries from Christianity's contact with different cultures and not forgetting the dangers of alterations which have sometimes occurred.
