The Nativity of John the Baptist celebrates the birth of John the Baptist. It is one of the oldest festivals of the Christian church, being listed by the Council of Agde in 506 as one of that region’s principal festivals, where it was a day of rest and, like Christmas, was celebrated with three Masses: a vigil, at dawn, and at midday.
The life of John the Baptist has long been interpreted as a preparation for the coming of Jesus Christ, and the circumstances of his birth, as recorded in the New Testament, are miraculous. The sole biblical account of the birth of John the Baptist comes from the Gospel of Luke. In the Gospel, Luke gives emphasis to the announcement of his birth and the event itself, both set in parallel to the same occurrences in the life of Jesus.
Saint John the Baptist attracted countless people to the banks of the Jordan, and it occurred to some people that he might be the Messiah. But he constantly deferred to Jesus, even to sending away some of his followers to become the first disciples of Jesus.
Perhaps John’s idea of the coming of the Kingdom of God was not being perfectly fulfilled in the public ministry of Jesus. For whatever reason, when he was in prison he sent his disciples to ask Jesus if he was the Messiah. Jesus’ answer showed that the Messiah was to be a figure like that of the Suffering Servant in Isaiah. John himself would share in the pattern of messianic suffering, losing his life to the revenge of Herodias.
