Centuries after devout Christians embarked on drawn-out and arduous journeys to the Holy Land, a very unique crusade will reach Israel this week. Four Christians from Austria and Switzerland - two men and two women -- left Switzerland last June with the goal of crossing 4,300 kilometers by foot until they reach Israel. For seven months the four pilgrims marched in the sweltering heat and freezing cold, bearing it all for the sake of reaching the Holy Land in time for Christmas. Inevitably, at one stage they found themselves surrounded by Bashar Assad's soldiers who forced them to flee to the south by taxi. The four are set to reach their final destination on Wednesday and arrive at the Allenby Crossing from where they will march to Jericho. Their journey will officially conclude at a mass in the Church of the Nativity in Bethlehem on Friday.
