Iglesia Evangélica Luterana Boliviana (Bolivian Evangelical Lutheran Church) (IELB)
The Bolivian Evangelical Lutheran Church grew out of the work of the World Mission Prayer League from the USA, among Aymara Indians. In 1972, the American missionaries left the country, as the local people claimed greater participation in the decision-making bodies of the church. The Bolivian Evangelical Lutheran Church was constituted that same year. The church is composed entirely of indigenous people. It is the largest Amerindian Lutheran church on the continent.
The IELB's main priority is to promote a holistic approach to evangelism and service. The church is involved in a variety of projects: alternative agriculture, animal husbandry, provision of drinking water, educational campaigns to prevent cholera, formal education (elementary school), vocational training, and communication.
