O God, who on this day taught the hearts of your faithful people by sending to them the light of your 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 Jesus Christ your Son our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, for ever and ever. Amen.
Preface of Pentecost
Through Jesus Christ our Lord; according to whose most true promise, the Holy Spirit came down from heaven, lighting upon the disciples, to teach them and to lead them into all truth, giving them boldness and fervent zeal constantly to preach the Gospel to all nations; by which we have been brought out of darkness and error into the clear light and true knowledge of you, and of your Son Jesus Christ.
