God’s house is the whole world; God’s house is the Catholic Church; God’s house is also every faithful soul. But God inhabits the world in one way, the Church in another, and every faithful soul in yet a third. He is in the world as ruler of His kingdom; He is in the Church as head of the family in His own home; He is in the soul as the bridegroom in the wedding-chamber.
–Hugh of St. Victor (c. 1096–1141)
