John the Baptist

John the Baptist is the immediate precursor or herald of Jesus — the last and greatest of the Old Testament prophets, sent to prepare the way for the Messiah. He identified Jesus as "the Lamb of God who takes away the sin of the world" (John 1:29) and baptized him in the Jordan River (CCC 523, 720).

His Mission

John's mission was to prepare Israel to receive the Messiah by calling the people to repentance and baptizing them in the Jordan — a baptism of water for the forgiveness of sins, looking forward to the one who would baptize with the Holy Spirit (Matthew 3:11). Isaiah had prophesied him: "A voice cries in the desert: Prepare the way of the Lord" (Isaiah 40:3; CCC 717–720).

His Relationship to Jesus

John is the bridge between the Old and New Testaments. He concludes the prophetic tradition of Israel and inaugurates the Gospel of Christ. Jesus declared him the greatest of those born of women — yet "the least in the kingdom of heaven is greater than he" (Matthew 11:11). John's greatness is in pointing beyond himself entirely to Christ (CCC 523).

His Martyrdom

John was beheaded by Herod Antipas at the request of Herodias, whose adulterous union John had publicly condemned (Matthew 14:3–12). His death foreshadows and prefigures the death of Jesus — both are murdered by a political authority for speaking the truth (CCC 523).

Frequently Asked Questions

Was John the Baptist a relative of Jesus? Yes — the Gospel of Luke describes Elizabeth, John's mother, as a relative of Mary. At the Visitation, John leapt in Elizabeth's womb when Mary arrived — his first act of prophetic recognition of the Messiah, while both were still unborn (Luke 1:36, 41; CCC 717).
