First reading: Acts 12:24-13:5

The word of God continued to spread and to gain followers. Barnabas and Saul completed their task and came back from Jerusalem, bringing John Mark with them.

In the church at Antioch the following were prophets and teachers: Barnabas, Simeon called Niger, Lucius of Cyrene, Manaen, who had been brought up with Herod the tetrarch, and Saul. One day while they were offering worship to the Lord and keeping a fast, the Holy Spirit said, ‘I want Barnabas and Saul set apart for the work to which I have called them.’ So it was that after fasting and prayer they laid their hands on them and sent them off.

So these two, sent on their mission by the Holy Spirit, went down to Seleucia and from there sailed to Cyprus. They landed at Salamis and proclaimed the word of God in the synagogues of the Jews; John acted as their assistant.

Responsorial Psalm; Psalm 66(67):2-3,5-6,8

Let the peoples praise you, O God; let all the peoples praise you.

O God, be gracious and bless us
  and let your face shed its light upon us.
So will your ways be known upon earth
  and all nations learn your saving help.

Let the peoples praise you, O God; let all the peoples praise you.

Let the nations be glad and exult
  for you rule the world with justice.
With fairness you rule the peoples,
  you guide the nations on earth.

Let the peoples praise you, O God; let all the peoples praise you.

Let the peoples praise you, O God;
  let all the peoples praise you.
May God still give us his blessing
  till the ends of the earth revere him.

Let the peoples praise you, O God; let all the peoples praise you.
