|The long-term ministry of the Equipo Menonita del Chaco Argentino with indigenous churches is supported by Iglesia Menonita Bragado and the central region of the IEMA, the Pike and Sonnenberg Mennonite Churches in Ohio, and Mennonite Mission Network.||The focus of ministry in the Argentine Chaco is on Scriptures in indigenous languages. This has included translation, oral history, Bible studies and many forms of accompaniment. Currently International Partnership Associates Alfonsina and José Luis Oyanguren, sent by the Bragado Mennonite Church in Argentina, serve in the Chaco together with indigenous leaders. They focus on the development of the Castelli Bible Institute and related education projects. Production of El Mensajero, a church newsletter primarily in indigenous languages helps to connect some 300 indigenous churches across denominations.
||<p>The former Mennonite Board of Missions began mission work with the indigenous people in the Argentine Chaco in 1943. In the 1950s, the focus shifted from planting Mennonite churches to accompanying the emerging indigenous church. Mennonite Mission Network encouraged the church in its development of leaders and its unique style of worship and organization. In 1960, Iglesia Evangelica Unida (United Evangelical Church) was founded by 28 indigenous congregations in the Chaco.</p>
<p>In partnership with Mennonite Mission Network, primarily from 2004 - 2011, a large Mennonite Team included workers from the U.S., Argentina and Germany, serving as an intercultural, interdenominational, international team. In a fourteen year project, the Mennonite Team played a key coordination role with indigenous translators and the Argentine Bible Society in finishing the first complete Toba Qom Bible translation in 2014. A New Testament study guide was also published, and an Old Testament guide is in process.</p>
