Pentecost Sunday
Reading I: Acts 2:1-11 II: 1Cor 12:3-7,12-13
19 On the evening of that day, the first day of the week, the doors being shut where the disciples were, for fear of the Jews, Jesus came and stood among them and said to them, "Peace be with you."
20 When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord.
21 Jesus said to them again, "Peace be with you. As the Father has sent me, even so I send you."
22 And when he had said this, he breathed on them, and said to them, "Receive the Holy Spirit.
23 If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained."
The disciples receive the Holy Spirit and Jesus' mission.
Jesus breathed on the disciples to give them new life as children of God. With this new life or new force, they will be able to fight against sin or the forces of evil.
Baptism gives us the grace of new birth in God the Father, through his Son, in the Holy Spirit. For those who bear God’s Spirit are led to the Word, that is, to the Son, and the Son presents them to the Father, and the Father confers incorruptibility on them. And it is impossible to see God’s Son without the Spirit, and no one can approach the Father without the Son, for the knowledge of the Father is the Son, and the knowledge of God’s Son is obtained through the Holy Spirit.
