A blessed Pentecost to all of our readers!
From the Book of Common Prayer:
O God, who on this day
didst teach the hearts of thy faithful
people by sending to them the light of thy Holy Spirit:
Grant us by the same Spirit
to have a right judgment in all things,
and evermore to rejoice in his holy comfort;
through the merits of Christ Jesus our Savior,
who liveth and reigneth with thee,
in the unity of the same Spirit,
one God, world without end. Amen.
