The Day of Pentecost is the conclusion of the Easter season. The feast of the Resurrection, Easter Day, stands at one end of the church’s calendar and the Day of Pentecost, fifty days after Easter, stands at the other. This is to say that Pentecost should not be thought of as something separate from Easter but the consequence of Easter. God raised Jesus from the dead, Jesus appears to his disciples, Jesus ascends into heaven, God sends the promised holy Spirit [St John 16:4-15; St Luke 24:49; Acts 1:8], the disciples become the embodiment of Jesus’s ministry in the world. The Day of Pentecost, the power that comes to the church, to the disciples, through the Spirit is the logical [if you can use that word] outcome of the resurrection of Jesus.
The Resurrection of Jesus stands as God’s declaration that the vision of the world that Jesus preached and acted out was God’s true vision for the world. What Jesus said and did is what the world, what humanity, was always supposed to be. The Day of Pentecost shows us how God is going to make this vision come to life in the world. God is going to give power and strength to ordinary people and, through them, reshape the world.
One of the reasons we celebrate confirmations on the Day of Pentecost is that we are affirming with our lives that we believe God has called us to the mission and ministry of Jesus through our baptisms and we believe God gives us the strength do live out this mission and ministry.
