The theme of each Sunday is resurrection. During Sunday morning worship, through Word and Sacrament and community, we enact the new life made possible by the resurrection of Jesus the Christ.
Right now, that every-Sunday theme is embedded in the context of Pentecost. The season of Pentecost began with the great festival Sunday of Pentecost, when we celebrate the giving of the Holy Spirit to the Church (read Acts 2:1-21 again), and it extends until the first Sunday in Advent! The season of Pentecost raises our awareness of how God the Holy Spirit forms us in faith.
Here is a wonderful, ancient prayer for the season of Pentecost:
Almighty God, Father of our Lord Jesus Christ,
grant, we pray, that we might be grounded
and settled in your truth by the coming of
your Holy Spirit into our hearts.
What we do not know,
reveal to us;
What is lacking within us,
make complete;
That which we do know,
confirm in us;
And keep us blameless in your service,
through Jesus Christ our Lord.
Amen.
Clement of Rome (died c. 96)
