Missionary Alliance Christian Churches in Whidbey Island, Washington

An alliance is a relationship among people, groups, or states that have joined together for mutual benefit or to achieve some common purpose, whether or not explicit agreement has been worked out among them. Members of an alliance are called allies. Alliances form in many settings, including political alliances, military alliances, and business alliances. When the term is used in the context of war or armed struggle, such associations may also be called allied powers, especially when discussing World War I or World War II. A formal military alliance is not required for being perceived as an ally—co-belligerence, fighting alongside someone, is enough. According to this usage, allies become so not when concluding an alliance treaty but when struck by war.

Christian usually refers to:

A missionary is a member of a religious group sent into an area to promote their faith or perform ministries of service, such as education, literacy, social justice, health care, and economic development. The word "mission" originates from 1598 when the Jesuits sent members abroad, derived from the Latin missionem (nom. missio), meaning "act of sending" or mittere, meaning "to send". The word was used in light of its biblical usage; in the Latin translation of the Bible, Christ uses the word when sending the disciples to preach the gospel in his name. The term is most commonly used for Christian missions, but can be used for any creed or ideology.
