Old Testament: Ezekiel 37:1–14
Epistle: Acts 2:1–21
Gospel: John 15:26–27, 16:4b–15
We pray in the Collect, “O God, on this day You once taught the hearts of Your faithful people by sending them the light of Your Holy Spirit. Grant us in our day by the same Spirit to have a right understanding in all things.” Jesus explains the work of the Holy Spirit: “And when he comes, he will convict the world concerning sin and righteousness and judgment.” (Gospel, Jn 16:8). In the Second Reading in Acts 2, the Spirit is made manifest through the mighty rushing wind and tongues of fire as he gives the apostles the gifts needed to spread the Gospel, namely, the ability to speak in languages not known to them previously. And in the Old Testament Reading (Ezek 37:1–14), the prophet is led to the field of dry bones where he is given the very words to prophecy. The Spirit’s breath of life causes dead bodies to come alive with flesh and breath. All this is the necessary work of the Holy Spirit. And especially precious to us: our Comforter, our Helper, who gives us God’s Word to bear witness to the world (Jn 15:26).
