VATICAN CITY: The civil war in Syria will cast a long shadow on Pope Benedict’s trip to neighboring Lebanon next weekend, but the Vatican is “tranquil” about his security after receiving guarantees from the country’s fractious religious groups, the papal envoy to Beirut said Monday.

Archbishop Gabriele Caccia told Reuters he hoped the situation in Syria would not drown out the main purpose of the trip – to focus attention on the problems and aspirations of the entire Middle East.

“You certainly can’t close your eyes to a situation of violence. The drama in Syria looms over this trip but there is also the wider horizon of the Middle East,” Caccia said in a telephone interview from Beirut.

“The Syrian question takes priority because it is an emergency but the whole trip cannot be reduced to a political question regarding Syria,” he said.

There are fears that the Syrian conflict could spill over into Lebanon and reignite civil war among the country’s rival religious groups. Lebanon’s population is 60 percent Muslim with the rest almost all Christian.

While there have been fears in some quarters that the papal trip is too dangerous, Caccia said “I am as tranquil as humanly possible” and the Church had “reasonable guarantees” that the visit would not be disrupted.

“Clearly security forces are on alert. Security is always a priority during papal visits, particularly in this [regional] context, which is a heated one,” he said.

“But I must honestly say that as far as the Lebanese components are concerned, no sector has expressed opposition to this trip. All the communities – Christians, Muslims, Sunni, Shiite, Druze and Alawites – have reacted positively to the trip.”

Many Sunni Muslims in Lebanon actively support the mainly Sunni revolt against Syrian President Bashar Assad, a member of the minority Alawite faith which has links to Shiite Islam. Lebanese Shiites, among them Hezbollah, have mostly backed Assad.

Caccia said a delegation from Hezbollah visited Lebanon’s Maronite Christian patriarch recently and “expressed joy” at the pope’s trip.

“There have been contacts all around from the start. We always have to be alert because terrorist plots are a danger for all societies and the whole world. But the current context seems to give us reasonable guarantees, otherwise the trip would not have gone ahead,” he said.

Benedict, on his 24th trip outside Italy since his election in 2005, is making the three-day visit to issue a document known as a “apostolic exhortation” based on the results of a synod of bishops on the Middle East in 2010.

That synod tackled subjects such as regional security, the exodus of Christians from the area, and the need for a resolution to the Israeli-Palestinian conflict – all topics that are expected to be addressed in the papal document and in Benedict’s speeches.

During his visit to Lebanon, the pope is expected to hammer home his calls for an international solution to the conflict in Syria, where opposition groups say more 27,000 people have died in an uprising that has lasted more than 17 months.

“We know that it is not just an internal conflict. A geopolitical chess game involving big world powers is being played out around the Syria situation so it is difficult to imagine a purely local solution,” the envoy said.

“We can’t just sit and watch what is happening without trying to stop the useless violence, massacres and human dramas which will be the cause of more difficulties in the future,” he said.

Caccia hinted that the pope would encourage the reforming spirit of the so-called Arab Spring movement but stress that it could not be based on violence.

“This wind of spring is just starting. It will be a very long process and we don’t know how it will end but it is certainly motivated by ideas that are deep and undeniable for every human being, such as freedom, justice, solidarity with others and respect for diversity,” he said.

The pope is also expected to address the Vatican’s fears of an exodus of Christians leaving the Middle East because of war, instability and lack of economic opportunities.

“Christians are in the Middle East not because they arrived with a colonial empire. They are an original part of the landscape, they are citizens of these lands, they have roots in this land and they have a right to live in the place where they were born,” Caccia said.
