In Damascus, a few dozen Syrian Christians attended a service in the al-Zaytoun Church, joining Francis' invitation for a global participation in the day of fasting and prayer and to oppose outside military intervention in the conflict.
Greek Catholic Patriarch Gregorios III Laham of Antioch and All East presided, saying most countries supported a political solution to the crisis in Syria and few wanted military action. "This is the start of the victory," he told the Damascus faithful. "No to war. Yes for peace."
Francis announced the day of fasting and prayer September 1, alarmed at the acceleration of US threats to strike Syria after the chemical weapons attack.
Since then, the Vatican has ramped up its peace message, summoning ambassadors for a briefing by the Holy See foreign minister. Francis appealed directly to world powers at the Group of 20 meeting in Russia, urging them this week to abandon the "futile pursuit" of a military solution in Syria and work instead for a negotiated settlement.
Bishops around the world joined Francis in the daylong fast and organized similar vigils in their home dioceses. In Francis' native Argentina, human rights and religious groups held a vigil in Buenos Aires' Plaza de Mayo and in cities across the country. Vatican Radio reported similar initiatives were taking place throughout Italy, in Cuba and elsewhere. Even the grand mufti of Damascus, who thanked the pope for his initiative in a letter earlier this week, invited Muslims to join the fast in solidarity.
Vatican officials have stressed that Saturday's event was thoroughly religious, not political. But the gathering nevertheless took on the air of an anti-war rally, with protesters holding up Syrian flags and banners in the square reading "Don't attack Syria" and "Obama you don't have a dream, you have a nightmare." A few rainbow "Peace" flags fluttered in the breeze.
But by the time the vigil got under way, the posters and flags had mainly disappeared as a more religious tone took over, with leaders from a variety of Christian and non-Christian denominations joining cardinals, politicians and ordinary folk for the evening of prayer, hymns and meditation.
"This is already a success, the fact that all of us are here, Hindus, Christians, Buddhists, atheists," a Hindu believer named Anata said. Pilgrims "made an effort to fast, not to do many things, and come here from all over Italy and Europe. This is already a success."
The pope entered the square from the basilica steps, foregoing his usual high-spirited drive through in his open car - an indication of the sobriety of the evening, which capped a day of fasting for the pontiff.
The peace vigil marked something of a novelty for the Vatican: Nothing of its kind has ever taken place in St. Peter's Square, though popes past have participated in daylong peace prayers in places like Assisi, known for its peace-loving native son and the pope's namesake, St. Francis.
That's not to say popes haven't taken vigorous anti-war positions in the past: Pope Paul VI famously uttered the words "War never again, never again war" at the United Nations in 1965 as the Vietnam War raged, a refrain that has been repeated by every pope since. Pope John Paul II sent an envoy to President George W. Bush on the eve of the 2003 US-led invasion of Iraq urging him to stand down - to no avail.
Francis has condemned the use of chemical weapons in Syria, but has been careful not to lay blame on any one side, exhorting world leaders instead to focus on the plight of Syrian civilians and the need in general to end the violence.
Other church officials, both at the Vatican and in dioceses, have been more pointed in their criticism of any internationalisation of the conflict, saying US-French military strikes will only exacerbate the situation for civilians, particularly Christian minorities.
