Marriage is a particular form of the universal call to holiness that we all have. Regis and Libby Flaherty survey cultures throughout the ages to show from ancient Rome to today Christians have lived this radical call in the sanctuary of their homes. These Christians responded to their own call in marriage and became beacons of hope in dark times. This is what we must each do in our own age—opening ourselves to God, to hear His call, and embrace it, so that together we can fill the world with His light.
