Welcome back to the Sunday Mass notes for Pentecost Sunday. We open with the first reading from Acts that chronicled the Day of Pentecost when God sent the Holy Spirit to indwell the believers in the early church. Then we move onto the second reading from Saint Paul’s First Letter to the Corinthians and discuss the gifts of the Spirit. We conclude with the Gospel lesson from Saint John where we will examine what it means when Jesus said, “If you forgive the sins of any, their sins have been forgiven them; if you retain the sins of any, they have been retained” (John 20:23).
