To the pilgrim, then, who wended his way to the tombs of saints, and, in the crusade times, to the holiest of graves in Jerusalem, mediæval hospitality is mainly devoted. The crusaders were agents of especial power in the development of hospitality, since on his lengthy journey the pilgrim stood in need, not only of food and shelter, but also of convoy along roads perilous everywhere. The Knights of St. John set themselves these two tasks, to care for the pilgrims and escort them in safety, which is implied by their name “fratres hospitales S. Johannis.” In the rule of their order (ca. 1118) the foremost duty of lay as well as clerical brothers was to serve the poor, “our lords.” With like intent of safeguarding pilgrims the Order of Knights Templars was instituted in 1119, especially for the care of German pilgrims. We may venture to assume from their name, “Order of the German House of our dear Lady in Jerusalem,” that a homelike Madonna picture adorned their hospitable house as a pious welcome. Shakespeare has inimitably described the warlike duties of these orders, duties which went hand in hand with kindly care and hospitality, in the first part of “Henry IV”:-- “To chase these pagans, in those holy fields Over whose acres walk’d those blessed feet Which, fourteen hundred years ago, were nailed For our advantage, on the bitter cross.” These knightly orders, whose hospitable roofs originally sheltered the pious pilgrims bound for Jerusalem, also opened in welcome the gates of their proud houses at home, which still adorn more than one old German town. When Luther was summoned to Worms by the Emperor, in 1521, he stayed with the Knights of St. John. Here in this noble inn he exclaimed to his friends, after the ordeal, with upraised arms, and face shining with joy: “I am through, I am through.” Like an enduring rock he had stood his ground and had expressed his unalterable will to be a free Christian in those famous words: “Hier stehe ich, ich kann nicht anders, Gott helfe mir! Amen.”
