According to the Gospel of John, Andrew first introduced Simon Peter to Jesus.
John 1:40–42 says Andrew was one of the first disciples to follow Jesus after hearing John the Baptist. Andrew then found his brother Simon and brought him to Jesus, who gave Simon the name Cephas, translated as Peter.
Andrew is identified as Simon Peter’s brother and as a former follower of John the Baptist. In John’s Gospel, this introduction is an early sign of Andrew’s role in bringing people into contact with Jesus.
This episode is distinct from the Synoptic accounts, in which Jesus calls Simon and Andrew while they are working as fishermen by the Sea of Galilee. John’s narrative emphasizes personal testimony and recognition before describing the brothers’ fuller discipleship.
