The vision, call and energy for the Patagonia Mission Project emerged within the Mennonite Church in Argentina as far back as the mid-1990s. As the Mennonite churches in the Patagonia region began their work, they sought partners. In response to this challenge was born Arm in Arm—a cluster of people from Illinois congregations who came together to form a partnership for ministry with the Iglesia Evangélica Menonita Argentina and in collaboration with Mennonite Mission Network.
