In this posture of affairs, Luther reverted, with increased conviction, to his original opinion, that the future must be left with God alone, without trusting to the help of man. Hutten himself had written to him, during the Diet of Worms, as follows: 'I will fight manfully with you for Christ; but our counsels differ in this respect, that mine are human, while you, more perfect than I am, trust solely in those of God.' And when Hutten seemed really bent on taking the sword, Luther declared to him and to others, with all decision of purpose: 'I would not have man fight with force and bloodshed for the Gospel. By the Word has the world been subdued, by the Word has the Church been preserved, by the Word will she be restored. As Antichrist has begun without a blow, so without a blow will Antichrist be crushed by the Word.' Even against the Romish hirelings among the German clergy, he would have no acts of violence committed, such as were committed in Bohemia. He had not laboured with the German nobility to have such men restrained by the sword, but by advice and command. He was only afraid that their own rage would not allow of peaceful means to check them, but would bring misery and disaster upon their heads. His expectation--not indeed ungrounded--of the approaching end of the world, to which, as we have seen, he alluded in a letter to Spalatin on January 16, 1521, Luther now announced more fully in a book, written in answer to an attack by the Romish theologian Ambrosius Catharinus. He based his opinion on the prophecies of the Old and New Testament, on which Christian men and Christian communities, sore pressed in the battle with the powers of darkness, had been wont ere then to rely, in the sure hope of the approaching victory of God. Luther referred in particular to the vision of Daniel (chap. viii.), where he states that after the four great Kingdoms of the World, the last of which Luther takes to be the Roman Empire, a bold and crafty ruler should rise up, and 'by his policy should cause craft to prosper in his hand, and should stand up against the Prince of princes, but should be broken without hand.' He saw this vision fulfilled in the Popedom; which must, therefore, be destroyed 'without hand,' or outward force. St. Paul, in his view, said the same in the passage in which (2 Thess. ii.) he foreshadowed long before the Roman Antichrist. That 'man of sin' who set himself up as God in the temple of God, 'the Lord shall consume with the spirit of His mouth, and shall destroy with the brightness of His coming.' So, said Luther, the Pope and his kingdom would not be destroyed by the laity, but would be reserved for a heavier punishment until the coming of Christ. He must fall, as he had raised himself, not 'with the hand,' but with the spirit of Satan. The Spirit must kill the spirit; the truth must reveal deceit.
