Jesus may have walked on water and turned it into wine but the hefty water bill for one of the holiest sites of Christendom is proving a headache for the church.The Church of the Holy Sepulcher, said to be the site of Jesus' crucifixion and burial, is struggling with a NIS 9 million ($2.3 million) unpaid bill owed to the Jerusalem water company.This week the Greek Orthodox Patriarchate of Jerusalem, which has extensive and valuable property holdings in the Holy Land and maintains a headquarters in the ancient church, had its bank account frozen, said an official at water company Hagihon.
