Pope Francis flies to the West Bank on Sunday to start the most delicate part of his stay in the Middle East, with visits to the Palestinian Territories and Israel, where his every word will be scrutinized.
Church officials say his three-day tour of the region, which started on Saturday in Jordan, is purely focused on religious issues. However, the dividing lines of the generations-old Middle East conflict will be impossible to ignore.
Francis will fly straight by helicopter to Bethlehem, becoming the first pontiff to travel directly to the West Bank rather than enter via Israel - a decision hailed by Palestinian officials as a recognition of their push for full statehood.
The Pope is due to celebrate an open-air Mass in Bethlehem’s Manger Square, close to where Christians believe Jesus was born.
Underlining the power of symbolism, a mural has been erected there showing Jesus swaddled in a Palestinian keffiyeh, with his father, Joseph, also wearing the black and white headdress, made famous by the late Palestinian leader Yasser Arafat.
Authorities have likewise plastered images around the city comparing the experience of Palestinians to the suffering of Jesus, and officials have made sure the Pope will see the Israeli separation barrier that divides Bethlehem from Israel as he visits Palestinians at a nearby refugee camp.
Israel says the wall is needed to prevent attacks by militants.
His trip comes at a time of renewed uncertainty, with the latest in a long line of U.S.-backed peace talks collapsing last month amid mutual recrimination and no clear ideas emerging over how to end decades of bloodshed and deadlock.
The Vatican supports the vision of an independent Palestine living in peace alongside Israel, and Francis on Saturday called for a “just solution” to the conflict - the sort of neutral, anodyne language he is expected to adhere to during the stay.
Francis also appealed in Jordan for an end to Syria’s civil war, and in an unscripted message, called for arms makers to be converted to become “constructors or peace.”
After barely six hours in Bethlehem, Francis will head to Israel, but to avoid a diplomatic tangle, he has to get back in his helicopter and fly to Tel Aviv for a welcoming reception, rather than drive the short distance to Jerusalem.
Israel calls Jerusalem its eternal and undivided capital, having annexed Arab neighborhoods seized in the 1967 war, including the Old City, the site of the main religious shrines. The rest of the world has not recognized the annexation and leaders traditionally enter the country via Tel Aviv.
From there, he will get back in his helicopter and fly to Jerusalem for what he has said is the purpose of the whole trip - to commemorate the 50th anniversary of a historic meeting of Catholic and Orthodox Christian leaders, who moved to end centuries of bitter divisions between the two churches.
The Vatican’s yellow and white flags flutter from lampposts across the city, and posters of a smiling Francis have been strung up from numerous buildings, but that might be as much as many locals get to see of him.
His decision not to use a bullet-proof car means Israeli security officials are clearing the roads and creating numerous “sterile areas” ahead of his 24-hour stay in the city.
“He is a guest here and we would like to assure that he goes back home safe and sound,” said Oded Ben-Hur, a former Israeli ambassador to Holy See.
