“The Week of Prayer for Christian Unity is celebrated around the world January 18-25… This universal week of prayer encourages Christians of all denominations to meet, to participate in various liturgical and other community activities and to pray together that all may be one, as Christ desires (Ordo, 118).”
We are invited to pray for this intention using the collect from the Mass “For Unity of Christians”:
Almighty ever-living God,
who gather what is scattered and keep together what you have gathered,
kindly on the flock of your Son,
those whom one Baptism has consecrated may be joined together
by integrity of faith and united in the bond of charity.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.
