Confirmation is when those baptized as infants or small children affirm their faith in Christ and take responsibility for living out the Christian life as adults. But it is also a time when we pray for a deeper infilling and awareness of the Holy Spirit in our lives.
In the Episcopal Church the laying on of hands by the Bishop is the sign or sacrament of our confirmation, our confirming our faith. And just as the Holy Spirit came upon the Apostles at Pentecost, so the Bishop through their Apostolic succession pray for the candidates to be strengthened and filled with the person of the Holy Spirit.
We come to this sacrament expecting God the Holy Spirit to pour new grace into those coming in faith.
