Francis, an Argentine Jesuit, will be the fourth pope to visit the Holy Land after Paul VI's landmark visit in 1964.
In his Christmas address, Francis singled out the Holy Land for prayers, saying "Bless the land where you chose to come into the world, and grant a favorable outcome to the peace talks between Israelis and Palestinians."
As archbishop of Buenos Aires, the former Cardinal Jorge Mario Bergoglio — now Pope Francis — made interreligious dialogue a top priority, hosting an annual interfaith ceremony in the Argentine capital's cathedral to promote religious harmony and writing a book on faith with his good friend, Rabbi Abraham Skorka.
"We are hoping for a new glimmer of light from this visit in relations with the Orthodox, with Muslims and Jews," Monsignor William Shomali, auxiliary bishop in Jerusalem, told Vatican Radio on Sunday.
All three governments welcomed the papal visit.
The Palestinian news agency Wafa said President Mahmoud Abbas hoped it would "contribute to alleviate the suffering of the Palestinian people who aspire for freedom, justice and independence."
In Jerusalem, Israeli Foreign Ministry Yigal Palmor said Francis was "will be greeted as warmly as his predecessors were."
Jordan's Royal Palace said the Amman leg of Francis' visit — on May 24 — would mark a "significant milestone for brotherhood and forgiveness between Muslims and Christians and consolidates the message of peace."
Francis said his prime aim was to commemorate the 50th anniversary of the historic meeting in Jerusalem between Pope Paul VI and the then-spiritual leader of the world's Orthodox Christians, Ecumenical Patriarch Atengora.
Catholics and Orthodox have been divided since the Great Schism of 1054, precipitated largely by disagreements over the primacy of the pope.
Francis will be joined in Jerusalem by the current ecumenical patriarch, Bartholomew, who became the first ecumenical leader to attend a papal installation since the schism when he traveled to Rome for Francis' inaugural Mass in March. They will celebrate Mass together at the Church of the Holy Sepulchre, where the faithful believe Jesus was crucified and buried.
Francis' full itinerary hasn't been released, but Rabbi Skorka said he hopes the pope will stop at the Western Wall, the holiest site where Jews can pray in Jerusalem.
The Catholic Church in the Holy Land said the visit was aimed "mainly at spreading and promoting love, cooperation and peace among all inhabitants."
After decades of reluctance by the Vatican to recognize the Jewish state, the Polish-born John Paul II forged formal relations in 1993, following it up with an official visit to Israel in 2000 that included stops at the Holocaust memorial Yad Vashem and at the Western Wall, where he famously left a handwritten plea asking forgiveness for Christian persecution.
The German-born Pope Benedict XVI followed up nine years later with his own visit.
