First Reading
ROMANS 5:1-5

1Therefore, since we are justified by faith, we have peace with God through our Lord Jesus Christ. 2Through him we have obtained access to this grace in which we stand, and we rejoice in our hope of sharing the glory of God. 3More than that, we rejoice in our sufferings, knowing that suffering produces endurance, 4and endurance produces character, and character produces hope, 5and hope does not disappoint us, because God's love has been poured into our hearts through the Holy Spirit which has been given to us.

Responsorial Psalm
PSALMS 117:1-2

1Praise the LORD, all nations! Extol him, all peoples! 2For great is his steadfast love toward us; and the faithfulness of the LORD endures for ever. Praise the LORD!

Gospel
MARK 16:15-20

15And he said to them, "Go into all the world and preach the gospel to the whole creation. 16He who believes and is baptized will be saved; but he who does not believe will be condemned. 17And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; 18they will pick up serpents, and if they drink any deadly thing, it will not hurt them; they will lay their hands on the sick, and they will recover." 19So then the Lord Jesus, after he had spoken to them, was taken up into heaven, and sat down at the right hand of God. 20And they went forth and preached everywhere, while the Lord worked with them and confirmed the message by the signs that attended it. Amen.
