In this St Luke’s Church podcast, Ian Mobsby explores the theme of baptism in the Christian faith, and the role of John the Baptist in the lectionary reading for the Second Sunday of Advent.   John the Baptist was the last prophet of Israel and  what is called the Herald of the Messiah, taught a baptism of repentance and of purification.   Since then the Christian Church has baptised people as the beginning of the path of following Christ.
