Twelve Apostles

In Christian theology and ecclesiology, the apostles (Greek: ἀπόστολος, translit. apóstolos, lit. 'one who is sent away'), particularly the Twelve Apostles (also called the Twelve Disciples), were the primary historical disciples of Jesus, the central figure in Christianity. During the life and ministry of Jesus in the 1st century AD, the apostles were his closest followers and became the primary teachers of the gospel message of Jesus. The word disciple is sometimes used interchangeably with apostle; for instance, the Gospel of John makes no distinction between the two terms. In modern usage, prominent missionaries are often called apostles, a practice which stems from the Latin equivalent of apostle, i.e. , the source of the English word missionary. For example, Saint Patrick (AD 373–463) was the "Apostle of Ireland", and Saint Boniface (680–755) was the "Apostle to the Germans".

While Christian tradition often refers to the apostles as being 12 in number, different gospel writers give different names for the same individual, and apostles mentioned in one gospel are not mentioned in others. The commissioning of the Twelve Apostles during the ministry of Jesus is recorded in the Synoptic Gospels. After his resurrection, Jesus sent 11 of them (minus Judas Iscariot, who by then had died) by the Great Commission to spread his teachings to all nations. This event is commonly called the Dispersion of the Apostles. There is also an Eastern Christian tradition derived from the Gospel of Luke of there having been as many as 70 apostles during the time of Jesus' ministry. Prominent figures in early Christianity, notably Paul, were often called apostles, even though their ministry or mission came after the life of Jesus.
