Luther never wore sword in his life, except when he figured as Knight George in the Wartburg, and yet he never lacked sword to defend him when he was in danger. He was dismissed from the Diet at Worms with two powerful weapons unsheathed above his head — the excommunication of the Pope and the ban of the emperor. One is enough surely; with both swords bared against him, how is it possible that he can escape destruction? Yet amid the hosts of his enemies, when they are pressing around him on every side, and are ready to swallow him up, he suddenly becomes invisible; he passes through the midst of them, and enters unseen the doors of his hidingplace.
This was Luther’s second imprisonment. It was a not less essential part of his training for his great work than was his first. In his cell at Erfurt he had discovered the foundation on which, as a sinner, he must rest. In his prison of the Wartburg he is shown the one foundation on which the Church must be reared — the Bible.
