Pope Benedict arrives in Lebanon on Friday.
Hezbollah has hung banners along the airport highway greeting Benedict with a picture of him and texts in Arabic and French saying: "Hezbollah welcomes the pope in the homeland of coexistence".
The 85-year-old pope, on his fourth trip to the Middle East as pope, will stress unity among the different Christian churches in the region and peace between Christians and Muslims during the visit, which will be restricted to Beirut and its surroundings and end on Sunday.
On Friday, Benedict will issue a document along these lines known as an "apostolic exhortation", based on discussions among Catholic bishops at a Rome synod on the Middle East in 2010.
The pontiff will also hold two major open-air events and meet leaders of all Lebanon's Christian and Islamic communities, as well as the country's political leaders.
Christians now make up about 5 percent of the Middle Eastern population, down from 20 percent a century ago. Some estimates say their 12 million total could be halved by 2020.
The pope's message of peace will especially be aimed toward Syria, whose border is only 50 km (30 miles) away and where an opposition group says more than 27,000 people have been killed in an uprising against President Bashar al-Assad.
Clashes have occasionally spilled over into Lebanese territory, evoking fears of further fighting in a country still recovering from the sectarian civil war that raged from 1975 until 1990.
About two-thirds of Lebanon's Christians are in full communion with the Vatican, either as members of the five local churches linked to Rome - the Maronites, the largest group, and the Greek Melkite, Armenian, Syriac and Chaldean Catholics - or of the worldwide Roman Catholic Church itself.
There are also five Orthodox churches - the Greek, Armenian, Syriac, Assyrian and Coptic Orthodox - and small groups of Protestants, mostly Presbyterians and Anglicans.
