Mt 4: 18-22
As he was walking by the Sea of Galilee, he saw two brothers, Simon who is called Peter, and his brother Andrew, casting a net into the sea; they were fishermen.
He said to them, “Come after me, and I will make you fishers of men.”
At once they left their nets and followed him.
He walked along from there and saw two other brothers, James, the son of Zebedee, and his brother John. They were in a boat, with their father Zebedee, mending their nets. He called them, and immediately they left their boat and their father and followed him.

Catechism of the Catholic Church
878 Finally, it belongs to the sacramental nature of ecclesial ministry that it have a personal character. Although Christ’s ministers act in communion with one another, they also always act in a personal way. Each one is called personally: “You, follow me” in order to be a personal witness within the common mission, to bear personal responsibility before him who gives the mission, acting “in his person” and for other persons: “I baptize you in the name of the Father and of the Son and of the Holy Spirit . .”; “I absolve you . ..”
St. Andrew, Apostle
Andrew the Apostle (Greek: Ἀνδρέας, Andreas; from the early 1st century – mid to late 1st century AD), also known as Saint Andrew and called in the Orthodox tradition Prōtoklētos (Πρωτόκλητος) or the First-called, was a Christian Apostle and the elder brother of Saint Peter.
The name “Andrew” (Greek: manly, brave, from ἀνδρεία, Andreia, “manhood, valour”), like other Greek names, appears to have been common among the Jews, Christians, and other Hellenized people of Judea. No Hebrew or Aramaic name is recorded for him. According to Orthodox tradition, the apostolic successor to Saint Andrew is the Patriarch of Constantinople.
