Collect

Bountiful God, giver of all gifts,
who poured your Spirit upon your servant Barnabas
and gave him grace to encourage others:
help us, by his example,
to be generous in our judgements
and unselfish in our service;
through Jesus Christ your Son our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.

Post Communion

Almighty God,
who on the day of Pentecost
sent your Holy Spirit to the apostles
with the wind from heaven and in tongues of flame,
filling them with joy and boldness to preach the gospel:
by the power of the same Spirit
strengthen us to witness to your truth
and to draw everyone to the fire of your love;
through Jesus Christ our Lord.

(or)

Lord God, the source of truth and love,
keep us faithful to the apostles’ teaching and fellowship,
united in prayer and the breaking of bread,
and one in joy and simplicity of heart,
in Jesus Christ our Lord.
