Greek Melkite Catholic Archbishop Jean-Clement Jeanbart of Aleppo said that for the past 60 years, Syria has strived to become a modern secular state. Western support for militants against Syrian President Bashar Assad would destroy all such progress, he said at an Oct. 13 meeting in the House of Lords organized by Aid to the Church in Need, a Catholic charity helping persecuted Christians.

Christians in his country were instead supportive of Russian military intervention because it gave them fresh hope that the four-year war would end in a solution favourable to them, he told British politicians and Christian leaders at the meeting.

British Foreign Office Minister Tobias Ellwood disagreed with the archbishop's analysis, telling the meeting that the conflict would continue until Assad stepped down.

During his speech, Jeanbart said militants were "killing anyone who is saying anything about freedom, about citizenship, about religious liberty, about democracy."

"Please, I ask you, I beseech you to have another look at our situation to see what is underneath, what is happening," the archbishop said.

"It is terrible for us to see all the marvellous things we had destroyed for pretend democracy and freedom," he said.

"Our country was fighting for 50-60 years to become a secularist regime, a pluralistic country, to give citizens their rights of religion and freedom of choice ... and you are destroying this work and pushing on us fundamental jihadis who want to kill everyone who is not similar to them. They don't accept anyone who is different. Anyone who is not a fundamentalist Muslim has no rights — no right to live, no right to be in society, no right to be a citizen."

The archbishop told the meeting that Syrian Christians are suffering because rebels "have destroyed everything — our economy, our industry, our churches, everything."

"The most important thing we are suffering from is that they are destroying man. They are taking away our right to choose what we want to be."

Jeanbart said he was pleased to have the chance to speak directly to British politicians because Syria was being isolated and that news from the country was being "manipulated in an unacceptable way."

The perception that moderate rebel forces were fighting the government to win freedom and democracy was a "big lie," the archbishop told the meeting, adding that the war was waged between a modern secular state tolerant of religious minorities and jihadi groups who were massacring them.

He said Islamist rebel groups, who go under a variety of names, had slaughtered more than 50 Christians within the last month alone, most recently shooting dead three Assyrian Christians after a ransom for their lives was not paid.

"My colleagues — bishops, priests and faithful — in Syria now feel they have hope that the problems will be sorted and the war will finish since Russia intervened and struck Daesh (Islamic State) seriously," he added. "That is what they think."

The conflict in Syria has claimed about a quarter of a million lives and displaced some six million people, most of whom are living in camps along the country's borders, while thousands of others have entered Europe through Turkey.

In 2013, British Prime Minister David Cameron failed to persuade Parliament to support the bombing of the Syrian regime by the United Kingdom in support of moderate rebel groups. He is expected to try again for permission to intervene militarily within the next few weeks.

Critics of his policy, including Peter Ford, a former British ambassador to Syria, say such moderates scarcely exist, arguing that the forces arrayed against Assad are invariably extremists. They also claim that interventions in Iraq and Libya have proved disastrous.

But Ellwood told the meeting that Assad was an obstacle to peace because no "inclusive government" could ever be formed under his rule.

"The recent Russia action is a clear demonstration of the Assad regime's weakness," he said. "Assad cannot survive without Russian or Iranian support, and Assad cannot win the war in Syria.

"We don't buy for one moment his spurious argument that he can protect religious minorities," he added. "His actions in effect have fueled sectarian violence, and his regime is ultimately responsible for the deaths of hundreds of thousands of civilians, and as long as Assad is in power the conflict will go on."

He said that Britain was presently "supporting non-governmental efforts to promote dialogue between different ethnic and religious groups in Syria" in preparation for the reconstruction of the country after the fall of Assad.

It was also attempting to promote interfaith dialogue in Iraq, where Christians are suffering acute persecution, he said.

The meeting was also addressed by human rights activist Lord Alton of Liverpool; Timothy Cho, an exile from North Korea who has witnessed the public execution of Christians there; and Victoria Youhanna, a Nigerian woman who escaped from Boko Haram.

Youhanna told participants how she had personally witnessed the beheadings of Christian men after they refused to join Boko Haram.

Archbishop Silvano Tomasi, the Holy See's permanent observer to the United Nations in Geneva, detailed the efforts of the Vatican to end the global persecution of Christians.

"Freedom of conscience and religion is a fundamental human right violated with impunity with regard to Christians in the Middle East and regions of Africa, where Christians are made the target of unspeakable violence," he said. "Christians are decapitated, crucified and forced into exile and enslavement."

Such violence, largely at the hands of militant Muslim groups, was "emptying the Middle East" of the Christian presence, Tomasi said.
