Christian and Missionary Alliance churches in Hilo Hawaii, United States

A Christian mission is an organized effort to spread Christianity.[1] Missions often involve sending individuals and groups, called missionaries, across boundaries, most commonly geographical boundaries, for the purpose of proselytism (conversion to Christianity, or from one Christian tradition to another). This involves evangelism (preaching a set of beliefs for the purpose of conversion), and humanitarian work, especially among the poor and disadvantaged. There are a few different kinds of mission trips: short-term, long-term, relational and ones meant simply for helping people in need. Some might choose to dedicate their whole lives to missions as well. Missionaries have the authority to preach the Christian faith (and sometimes to administer sacraments), and provide humanitarian work to improve economic development, literacy, education, health care, and orphanages. Christian doctrines (such as the "Doctrine of Love" professed by many missions) permit the provision of aid without requiring religious conversion.
