“In the fourth century, with the conversion of the emperor Constantine to Christianity and the steady growth of the church, the relation of Christianity to the society underwent a gradual but momentous transformation. Constantine introduced laws that made Sunday a day of rest, thereby creating a new calendar and reordering the life of society to make space for Christian worship. He advanced legislation that discouraged the exposure of infants by indigent parents and saw to it that the public fisc would provide food and clothing to rear abandoned children. He built churches, not only in the new Christian city of Constantinople and the old capital, Rome, but also in Jerusalem, a city that would acquire potent symbolic significance in the public consciousness. As these new buildings displaced the temples built by former emperors the plan of cities began to reflect the presence of Christianity in the life of the empire. The most prominent public building became the church, and to this day one will find a church on the central public square of European cities” (Robert Louis Wilken, The Spirit of Early Christian Thought: Seeking the Face of God, 199-200).
