Lord Jesus Christ, our God, who is the Source of life and peace in heaven and on earth, pour out the grace of your peace on a world troubled by war and hatred.
Extinguish the differences and enmity between humans and pour into the hearts of all humility, peace, and goodness. Calm the warriors and give them wisdom.
Give help to the suffering, protection to the refugees or homeless, comfort to the alienated and sorrowful, and give us all the will and strength to help, with all our hearts, our brothers and sisters who suffer from war.
You said: Blessed are the peacemakers, for they will be called children of God. Teach us to seek to acquire peace of heart and peace among peoples, for, in the heart in which peace is found, there is no longer enmity, love of dominion or fear, but the consolation of the Holy Spirit, love of God and love of our neighbours.
For this we humbly pray to You, O Christ our God, for peace among people in every country, for peace among peoples, and for the welfare of the whole world, that we may live in harmony and may work without hindrance deeds pleasing to You, glorifying the philanthropic love of the Father and of the Son and of the Holy Spirit, now and ever and unto ages of ages.
Amen.
