This episode is titled “The Witness of Stones.”I’ve had the privilege of doing a bit of touring in Europe. I’ve visited the cathedral at Cologne, Germany on several occasions. I’ve been to Wartburg Castle where Luther hid out. Mrs. Communion Sanctorum and I did a 2-week tour of Florence and Rome for our 30th Anniversary. We saw lots of churches and cathedrals. No matter what your thoughts about medieval Christianity, you can’t help but be impressed by the art and architecture the period produced.Some modern Christians, especially those of the Evangelical stripe, visit a medieval European cathedral, and come away impressed at the architecture, but mystified and maybe, a few anyway, a bit angry.Mystified on WHY people would go to such extremes to build such an immense and impressive structure. Angry at the massive expense such a structure meant.This episode seeks to explain the why behind medieval cathedrals.Churches in general and cathedrals in particular served two main purposes. First, the building was a place for worship; that worship being centered on the Mass. Second, the church was a place of instruction.The architecture was used as a tool for BOTH of these.In an age when only a small portion of society was literate, church buildings became a kind of “book in stone,” telling God’s story in the paintings and carvings that adorned the walls, and later, in the dazzling light of stained glass windows.Churches and cathedrals were made elaborate because of the theology of the Mass that we’ve looked at in the episode on the Eucharistic controversy. While the debate was long, the Church eventually settled in on the doctrine of transubstantiation; the belief that at the words of the priest, the bread and wine of Communion are transmuted into the literal body and blood of Christ. A portion of the consecrated host is kept in a container called a tabernacle, making the church into a house that holds the most precious thing in the universe; the body of Christ. It’s for this reason churches have long been regarded as sacred refuges. The church’s specialness derived from the presence of the host. And of course, that host deserved a house worthy of its importance.Think of the consecrated host as the finest gem. Such a jewel deserves an elaborate setting. It was this mentality that fueled the building of Europe’s Medieval Cathedrals. While churches were the meeting place of the faithful, their primary function was to serve as the location where the great miracle of transubstantiation took place.Following the Edict of Milan ending official persecution of Christians, the first church buildings were built in the same pattern and plan as Roman basilicas. These were civil government buildings used for a variety of purposes but officially designated as the hall where the king held court. The Roman basilica was in the shape of a capital “T.” Churches built in the 7th thru 11th C, a period called Romanesque, were built in a small “t” floor plan. The addition of the space at the top of the “t”, called the apse, was to provide room for the clergy who became increasingly distinct from the laity. As more priests and monks were added to the choir, the apse grew.Another major change in Romanesque churches was their roofs. They went from wood to stone. Stone roofs were possible because of the use of semi-circular arches that supported the additional load. When arches transect each other, it forms a vault. The challenge these arches, vaults, and stone roofs put on builders was the lateral stress they exerted. The weight of all that stone had to go somewhere and where it went was to the walls of the church. To keep them from toppling over, they were made sturdier by adding weight and width. So Romanesque churches are massive, imposing structures of thick walls and few windows.In the mid-12th C, Romanesque architecture gave way to a new movement called Gothic. That label was applied much later by those who
