Metropolitan Hilarion of Russia left little room for doubt about his priorities when offered a few moments to speak during the Vatican's tense Synod on the Family.

"Militant secularism" was on the rise, he said last fall. Thus, Catholics and Orthodox Christians should stand united while defending the "traditional Christian understanding of the family," "marriage as a union between a man and a woman" and the "value of human life from conception till natural death."

But most of all, Moscow's top ecumenical diplomat wanted to talk about martyrs -- new martyrs.

Consider Iraq, home to 1.5 million Christians a few years ago. Today, 150,000 remain while the "others were either exterminated or expelled," he said. Then look at Syria, Egypt, Nigeria, Pakistan, Libya and elsewhere.

"We are deeply concerned about the humanitarian catastrophe … unfolding in Syria, where militant Islamists are seeking political power," he said. Wherever jihadists "come to power, Christians are being persecuted or exterminated. Christian communities in Syria and other countries of the Middle East are crying for help, while the mass media in the West largely ignore their cries and the politicians prefer to close their eyes."

It was a foretaste of the historic "airport summit" declaration signed in Cuba by Pope Francis and Patriarch Kirill, leader of the Orthodox Church of Moscow and all Russia.
