The latest issue of Dabiq, the propaganda magazine of ISIS - or ISIL, or the Islamic State, call them what you will - contains a declaration of war against Christians. The front cover shows a picture of St Peter's in Rome flying the black ISIS flag.
"We will conquer your Rome, break your crosses, and enslave your women," they say. "If we do not reach that time, our children and grandchildren will reach it, and they will sell your sons as slaves at the slave market."
Meanwhile. a letter has been sent to the heads of state of 95 countries calling for urgent, determined action to halt the brutal persecution of Christians in the Middle East. The letter was signed by International Christian Embassy Jerusalem executive director Dr Jurgen Buhler, World Jewish Congress president Ronald S. Lauder, and Dr William M. Wilson, chairman of the Empowered21 Global Council.
Dr Buhler said the participation of the head of the main umbrella organisation representing world Jewry, together with leading evangelical ministries, made the event "historic." "Western churches have to do more to bring the suffering of our fellow believers to the forefront worldwide. To have a prominent global Jewish leader lend his voice to this moral call for protecting the region's persecuted Christians is unprecedented in modern times."
Father Gabriel Naddaf, a Greek Orthodox priest in Israel, told the UN Human Rights Council in Geneva in September that some 120,000 Christians have been killed each year in the Middle East for the last 10 years. That meant that every five minutes a Christian was killed because of his faith.
"Those who can escape persecution at the hands of Muslim extremists have fled. Those who remain exist as second if not third class citizens to their Muslim rulers."
Israel was the only place where Christians in the Middle East were safe. He appealed to the council's 47 member nations to "end your witch hunt of the only free country in the region."
Some 4,500 Christians from 80 countries have been in Jerusalem this week to celebrate the Feast of Tabernacles. A prayer vigil, organised by the International Christian Embassy Jerusalem, was held at the southern wall of the Temple Mount, adjacent to the Hulda Gate, on Wednesday. The Chief Rabbinate in Jerusalem issued a ban on Jewish participation.
The embassy said the prayer event was "for pilgrims only" and was "not in any way an interfaith event."
