Biblical foundations
The word mission (Latin: missio), as a translation of the Greek apostolē, “a sending,” appears only once in the English New Testament (Galatians 2:8). An apostle (apostolos) is one commissioned and sent to fulfill a special purpose. The roots of mission, Christians have believed, lie in God’s active outreach to humanity in history—as a call to those able to fulfill the divine purpose, among them Abraham, Moses, Jonah, and Paul. The New Testament designated Jesus as God’s apostle (Hebrews 3:1). Jesus’ prayer in The Gospel According to John includes the words “As thou didst send me into the world, so I have sent them into the world.… [I pray also] for those who believe in me through their word, that they may all be one…so that the world may believe that thou hast sent me” (John 17:18, 20–21). Moreover, the “Great Commission” of Jesus declares: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you; and lo, I am with you always, to the close of the age” (Matthew 28:19–20; compare Mark 16:15, Luke 24:47, John 20:21–22, and Acts 1:8).
