13 Jesus went up into the mountain, and called to himself those whom he wanted, and they went to him. 14 He appointed twelve, that they might be with him, and that he might send them out to preach, 15 and to have authority to heal sicknesses and to cast out demons: 16 Simon, to whom he gave the name Peter; 17 James the son of Zebedee; John, the brother of James, and he called them Boanerges, which means, Sons of Thunder; 18 Andrew; Philip; Bartholomew; Matthew; Thomas; James, the son of Alphaeus; Thaddaeus; Simon the Zealot; 19 and Judas Iscariot, who also betrayed him.

Mark 3:13-19 - World English Bible

Mark's gospel portrayed Jesus like Moses, going up the mountain. Instead of praying or receiving a revelation, he called men to become apostles, the founding structure of the Church. The apostles continued the mobile ministry of the Lord, both in word and power.

We can assume Mark named the apostles in order of prominence, and not in an sense of symmetry. Simon Peter was first, then James and John, then Peter's brother Andrew, and finally the rest. Notice the emphasis on James and John as the sons of Thunder, given their nickname in Greek (Zebedee) and Hebrew (Boanerges). Also, notice Judas was mentioned last as a place of shame.

As Jesus called his disciples to evangelize, he calls us by name to do the same. What have you done this week to spread the Good News?
