When the great Church of Holy Wisdom (the Hagia Sophia) was completed in Constantinople they hung thousands of lamps in it. The lights shone through a corona of windows in the dome, so that a sailor on the Bosporus could find his direction not only by the stars but by the light from the church. One writer of the time said, "It not only guides the merchant at night, it also shows the way to the living God." The concept of church as a lighthouse is not limited to location or architecture. Spiritually, every church must send out such true light that those who have wandered far from God can find their way home.
