For most of this century, churches across the country kept their doors unlocked 24 hours a day. Church was a place to head any time, for sanctuary. Today, you would be hard-pressed to find a church, in the city or the country, without a lock on its door. Burglary and theft of church property; from electronic equipment to religious articles, has become common. In a recent incident in Fargo, police caught a man they think is responsible for a series of burglaries at area churches. Church officials realize their sanctuaries are no longer immune from crime. Now they face the task of balancing locked doors with open arms.
