From among the many disciples who followed him, Jesus the Messiah chose twelve, corresponding to the number of Israel's tribes, and gave them the title of apostle.
The term ‘apostle’ comes from the ancient Greek ἀπόστολος / apóstolos, generally meaning a ‘messenger’ entrusted with a mission. In the Septuagint, the Greek version of the Bible, this word is applied to individuals; it translates the Hebrew shaliah, ‘plenipotentiary envoy’. The word is formed in ancient Greek from ἀπὸ, indicating sending or mission, and στέλλω, meaning to arrange or send.
These men, having become ambassadors of God's kingdom, will be given the power to heal the sick and proclaim the message of salvation. Jesus the Messiah thus delegates a degree of authority to them. After his death, they will be regarded as the pillars of the Church. Their reputation will ensure that the accounts of their testimonies, which they will write down, are naturally accepted.
The difference between their decision to follow this new Teacher in Judea (PER033, PER034), their calling on the shores of the (PER054, PER066) and this appointment is explained in the appendices cited at the beginning of this paragraph. We observe the organisation of a rapidly expanding work. This structure makes it easier to meet the crowd's many needs and also prepares for the future, particularly after the crucifixion.
These apostles, or ambassadors, will receive specific training from the Teacher. They will form a very close-knit group recognised and respected by the Church (Acts 5.13).
We observe that Jesus the Messiah chose his twelve apostles after a night of prayer, as Luke reports. Despite his divinity, Jesus did not act independently but always in harmony with the Father. Thus, the Trinity—Father, Son and Holy Spirit—formed a unity.
Several questions then arise: Was he praying to discern the next stage in developing his work? Was he seeking to know these men's identities? Was he imploring divine support for these men in their ministry?
We believe Jesus knew the time had come to select twelve men to prepare them for the arduous task of succeeding him (John 17.15). He knew the motives of the disciples who followed him, so choosing twelve of them seems quite natural. Did he know then that Judas Iscariot would betray him? Was he aware that he would steal money from the purse for which he was responsible? We offer elements of an answer in appendix ANN032: Judas Iscariot.
Jesus the Messiah was aware of his disciples' difficulties in understanding his work and believing in his omnipotence. This leads us to think that his prayers sought God's confirmation of the list of names of these men called to continue his work after his death, and the abilities they needed to carry out this difficult task.
We discuss the omniscience of Jesus the Messiah in the previously cited appendix. That is why we do not go into detail here.
