The call of the first disciples of Jesus is a key episode in the life of Jesus in the New Testament. It appears in Matthew 4:18–22, Mark 1:16–20 and Luke 5:1–11 on the Sea of Galilee. John 1:35–51 reports the first encounter with two of the disciples a little earlier in the presence of John the Baptist. Particularly in the Gospel of Mark, the beginning of the Ministry of Jesus and the call of the first disciples are inseparable.
In the Gospel of John the first disciples are also disciples of John the Baptist and one of them is identified as Andrew, the brother of Apostle Peter:
The next day John was there again with two of his disciples. When he saw Jesus passing by, he said, "Look, the Lamb of God!" When the two disciples heard him say this, they followed Jesus.... Andrew, Simon Peter's brother, was one of the two who heard what John had said and who had followed Jesus. The first thing Andrew did was to find his brother Simon and tell him, "We have found the Messiah".
Andrew is often called the Protokletos or "first-called".
The Gospel of Matthew and the Gospel of Mark report the call of the first disciples by the Sea of Galilee:
As Jesus was walking beside the Sea of Galilee, he saw two brothers, Simon called Peter and his brother Andrew. They were casting a net into the lake, for they were fishermen. "Come, follow me," Jesus said, "and I will make you fishers of men." At once they left theirhim.
