Details from The Daily Beast:
Egyptian security forces wielding assault rifles peer warily into the cars at each of the three checkpoints visitors must go through before reaching the ancient monasteries here about 60 miles west of Cairo. At the biggest checkpoint, on an exposed crossroads, young officers in bullet-proof vests are burning an upturned tree trunk to try to keep warm and to make some tea while waiting, and watching for threats.
During each stop, cars are searched meticulously, identity papers are collected, and visitors gently interrogated. The authorities don’t want to take any chances near a holy site that will soon be the focal point of a major Christian pilgrimage at high risk of attacks by the Egyptian branch of the so-called Islamic State. It could be the target of other groups as well, like the mob that just stormed a church in Giza, across the Nile from Cairo, on Friday.
Coptic Christians believe the Holy family—Jesus, Mary and Joseph—rested here in Wadi Natrun more than 2,000 years ago as they fled the persecution of King Herod shortly after Jesus was born. Now Christians are facing violent persecution by terrorists from the affiliates in Egypt of the so-called Islamic State, and sometimes violent friction with other groups as well.
Although it appears nobody was killed in the Giza incident, an established church that never won official government authorization for services was attacked, ransacked, and some of the parishioners beaten.
…Here in Wadi Natrun the Syrian Monastery, as it is called, is especially important because of its direct association with the story of Christ. The details of the trip to Egypt made by Jesus, Mary and Joseph are not included in the Bible, which has only one reference to “the flight into Egypt” in Matthew 2:13-2:15. But according to Coptic beliefs the family fled Bethlehem through North Sinai, down to what is modern day Cairo, before crossing to the Delta, hiding in Wadi Natrun, and eventually fleeing south to Upper Egypt.
And it is precisely that journey that the government in Cairo and, indeed, the Vatican now want to promote, despite threats by ISIS to launch further attacks on Egypt’s largest minority.
