Jesus' disciples
Before his baptism, Jesus did not have formally identified disciples. The Gospels suggest that he began to gather followers after his baptism by John the Baptist, when he started his public ministry. However, there were individuals, such as John the Baptist's own disciples, who recognized Jesus' significance before his baptism. The formal calling of his disciples, as recorded in the Gospels, occurs after this event.
