Lectionary for this day - This has all the readings and Gospel
Acts 2:42-47 - Communal Life -- The first of three summary passages (along with Acts 4:32–37; 5:12–16) that outline, somewhat idyllically, the chief characteristics of the Jerusalem community: adherence to the teachings of the Twelve and the centering of its religious life in the eucharistic liturgy (Acts 2:42); a system of distribution of goods that led wealthier Christians to sell their possessions when the needs of the community’s poor required it (Acts 2:44 and the note on Acts 4:32–37); and continued attendance at the temple, since in this initial stage there was little or no thought of any dividing line between Christianity and Judaism (Acts 2:46).
1 Peter 1:3-9 - Blessing
A prayer of praise and thanksgiving to God who bestows the gift of new life and hope in baptism (new birth, 1 Peter 1:3) through the resurrection of Jesus Christ from the dead. The new birth is a sign of an imperishable inheritance (1 Pt 1:4), of salvation that is still in the future (to be revealed in the final time, 1 Pt 1:5)
As the glory of Christ’s resurrection was preceded by his sufferings and death, the new life of faith that it bestows is to be subjected to many trials (1 Pt 1:6) while achieving its goal: the glory of the fullness of salvation (1 Pt 1:9) at the coming of Christ (1 Pt 1:7).
