Entrance to the crypt of the Glasgow Cathedral. Built before the Reformation from the late century onward and serving as the seat of the Bishop and later the Archbishop of Glasgow, the building is a superb example of Scottish Gothic architecture.
One symbol of the Eucharist is the chalice. The chalice holds the wine, that, during transubstantiation, becomes the Blood of Christ. We drink the wine to commemorate the Last Supper when Jesus told his disciples to drink, in memory of him.
