RABAT, Morocco — In what’s rapidly becoming the new papal normal, on the first day of his visit to Morocco, Pope Francis once again surprised friends and foes alike by signing an appeal that wasn’t on his schedule, this time on Jerusalem – calling for the city to be preserved as a “patrimony of humanity,” where followers of the three monotheistic religions are free to worship.

“We consider it important to preserve the Holy City of Jerusalem/Al-Quds Acharif as the common patrimony of humanity, and especially the followers of the three monotheistic religions, as a place of encounter and as a symbol of peaceful coexistence where mutual respect and dialogue can be cultivated,” says the short declaration signed by Pope Francis and King Mohammed VI.

Jerusalem’s multi-religious character, as well as the spiritual dimension and its particular cultural identity, must be “protected and promoted” so that Jews, Muslims and Christians all have “full freedom of access” and their “right to worship” is guaranteed, the two leaders said.

Francis and King Mohammed said that from this city, believers should be free to “raise their prayers to God, the creator of all, for a future of peace and fraternity on the earth.”

The appeal comes three days after the King of Jordan, Abdullah II, visited Mohammed VI seeking his support to preserve the custodianship the Jordanian leader currently exercises over the holy sites in Jerusalem, which he perceives to be threatened by President Donald Trump’s decision to move the U.S. embassy in Israel to Jerusalem.

Jordan’s monarchy has managed the Al Aqsa Mosque, the Dome of the Rock and the Church of the Holy Sepulcher in Jerusalem since 1946. Jordan had control over East Jerusalem and the West Bank until they lost to Israel during the 1967 Six-Day War.

Two decades later, the kingdom renounced claims to the territory, but the peace treaty signed in 1994 states that Israel will respect the role the Hashemite Kingdom of Jordan has over these sites in Jerusalem. It also says that when negotiations on the permanent status will take place, “Israel will give high priority to the Jordanian historic role in these shrines.”

Israel, the Palestinian Authority, the Arab League, the U.S., the European Union and Turkey all recognize Jordan’s custody of the Muslim and Christian sites in Jerusalem.

During his last trip, to United Arab Emirates, Francis also signed a declaration that hadn’t been announced when the program for the trip was released. On that occasion, together with the Grand Imam of Cairo’s Al-Azhar University, Sheikh Ahmed el-Tayeb, he signed a joint statement on “Human Fraternity” establishing the relationship between Catholics and Muslims as brothers, with a common mission to promote peace.

When it comes to the Holy Land, the Vatican supports a “two-state solution” with independence, recognition and secure borders for Israel and Palestine. The Holy See has consistently called for a special status for Jerusalem, particularly its Old City, in order to protect and guarantee access to the holy sites of Judaism, Christianity and Islam.

In 2017, Francis was part of a chorus of international leaders who criticized the decision of the Trump administration to recognize Jerusalem as the capital of Israel, expressing alarm that the announcement would provoke new tensions.

“I cannot remain silent about my deep concern for the situation that has developed in recent days,” Francis said a few days after Trump announced he would move the U.S. embassy from Tel Aviv to Jerusalem. “And at the same time, I wish to make a heartfelt appeal to ensure that everyone is committed to respecting the status quo of the city, in accordance with the relevant resolutions of the United Nations.”

“Jerusalem is a unique city,” Francis said at the time. “Sacred to Jews, Christians and Muslims, where the Holy Places for the respective religions are venerated, and it has a special vocation to peace.”

“I pray to the Lord that such identity be preserved and strengthened for the benefit of the Holy Land, the Middle East and the entire world, and that wisdom and prudence prevail, to avoid adding new elements of tension in a world already shaken and scarred by many cruel conflicts,” he said.
