They are encouraging us to use this prayer:
God of all peoples, acknowledging the significance of Jerusalem and the Holy Land in the history and lives of Jews, Christians and Muslims; and aware of political and social conflicts in the State of Israel and surrounding nations, and global involvement and tensions focused on this region; we pray for justice and lasting peace, compassion and hope for all peoples of these lands. As you hear the cries of those who suffer, grant them new life. Continue to uphold the Evangelical Lutheran Church of Jordan and the Holy Land and Bishop Ibrahim Azar, the Episcopal Diocese of Jerusalem and Archbishop Suheil, and supporting organizations and agencies working for the well being of all. Amen.

At the 2013 Joint Assembly, General Synod passed a resolution to “observe the Seventh Sunday of Easter, commonly known as the Sunday after Ascension Day, as Jerusalem Sunday.” For 2019, the theme for Jerusalem Sunday is Multi-Narrative Pilgrimage.
Jerusalem Sunday is an opportunity for Anglicans in Canada to learn more about and support God’s mission in the Diocese of Jerusalem. Parishes are encouraged to use liturgical resources . . . in celebration of Jerusalem Sunday. Parishes and individuals are also invited to make an offering in support important health care work in the Diocese of Jerusalem.
In a letter to Archbishop Fred Hiltz, Primate of the Anglican Church of Canada, the Most Rev. Suheil Dawani, Anglican Bishop in Jerusalem, expressed his gratitude for Jerusalem Sunday celebrations. “It is a tremendous encouragement and further testimony to our oneness in the Body of Christ and our bond-of-affection as members of the Anglican Communion.”
