In today’s Gospel, we see the mission of John the Baptist approaching its fulfilment. The Baptist made it clear from the start that he himself was not the Christ, but the prophet sent by God to prepare the way. Now, John the Baptist sees Jesus, recognises him as the Lamb of God and points him out to his disciples. Jesus is the one whose coming John was sent to proclaim; the Chosen One of God.
As disciples of Christ, we have been baptised with the Holy Spirit and set free from our sins. We too are called to see, recognise and bear witness, as the Baptist did. This is how the Church can be a light to the nations, as Isaiah foretold. This is how, as St Paul says, we will take our place among the saints – the vast assembly of believers who acknowledge Christ as Lord. Every baptised Christian is called to witness.
