1. The meaning of confirmation
What we now call confirmation was originally part of a wider ceremony of Christian initiation and only became a separate rite when bishops were no longer able to preside at all baptisms.
As a separate rite, confirmation marks the point in the Christian journey at which the participation in the life of God’s people inaugurated at baptism is confirmed by the bishop by the laying on of hands, and in which those who have been baptised affirm for themselves the faith into which they have been baptised and their intention to live a life of responsible and committed discipleship. Through prayer and the laying on of hands by the confirming bishop, the Church also asks God to give them power through the Holy Spirit to enable them to live in this way.
When confirmation is part of a combined rite including adult baptism it has a slightly different significance. In this case, as in the traditional Western service of initiation mentioned above, the confirmation element signifies the gift of the Holy Spirit following on from baptism in water. The biblical model for this is Christ’s own baptism in which, the gospels tell us, the Spirit descended on Him when He came up out of the water after having been baptised by John the Baptist (Matthew 3:16-17, Mark 1:9-11, Luke 3:21-22, John 1:32-33).
