The reading is from St. Paul's Letter to the Ephesians 1:1-9

Paul, an apostle of Christ Jesus by the will of God, To the saints who are at Ephesos and faithful in Christ Jesus: Grace to you and peace from God our Father and the Lord Jesus Christ. Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. He destined us in love to be his sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace which he freely bestowed on us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace which he lavished upon us in all wisdom and insight the mystery of his will, according to his purpose.
