During the Middle Ages, an allegorical approach to the Bible prevailed. Many theologians abandoned a literal understanding of Scripture and instead began looking for spiritual parables, often turning history into allegory. The Reformation changed all that as the Reformers called the church back to the authority of Scripture. They championed a return to sound biblical interpretation - reading the Bible carefully in context. In this booklet, Dr. Joel Beeke examines the writings of Reformers such as Martin Luther and John Calvin to determine what they believed and taught about the days of Genesis 1, arguing that a robust doctrine of creation provides a strong foundation for our faith!
