VATICAN CITY — The Vatican concluded its first treaty that formally recognizes the State of Palestine, with an agreement on Catholic Church activities in areas controlled by the Palestinian Authority, the Holy See said on Wednesday.

The agreement “aims to enhance the life and activities of the Catholic Church and its recognition at the judicial level,” said Monsignor Antoine Camilleri, the Vatican’s deputy foreign minister, who led its six-person delegation in the talks.

The text of the treaty has been concluded and will be officially signed by the respective authorities “in the near future,” a joint statement released by the Vatican said.

Vatican officials stressed that although the agreement was significant, it certainly did not constitute the Holy See’s first recognition of the State of Palestine.

“We have recognized the State of Palestine ever since it was given recognition by the United Nations and it is already listed as the State of Palestine in our official yearbook,” Vatican spokesman Father Federico Lombardi said.

On November 29, 2012, the U.N. General Assembly adopted a resolution recognizing Palestine as an observer non-member state. This was welcomed at the time by the Vatican, which has the same observer non-member status at the UN.

The treaty announcement comes days before Francis is to meet Palestinian President Mahmoud Abbas, who plans to attend a Mass on Sunday that will make saints of two Palestinian-born nuns who lived in the 19th and early 20th centuries.

During a three-day visit to the Middle East a year ago, Pope Francis delighted his Palestinian hosts by referring to the “state of Palestine”, giving support for their bid for full statehood recognition, and the new treaty further solidifies the relationship between the Vatican and Palestinians.

European Jewish Congress President Moshe Kantor called the treaty “unfortunate”, saying it would “diminish the chances of a negotiated peaceful resolution of the conflict and embolden extremists”.

Abraham Foxman of the Anti-Defamation League said the treaty was “premature” and said it would undermine a negotiated, two-state solution to the conflict.

Israel’s Foreign Ministry said it was “disappointed” by the Vatican’s decision, and that the recognition would “not advance the peace process.”
