But at the same time the impetuous reformer, as if restrained by a superior power, refused to employ the anathemas and thunders of the Word, and became an humble pastor, a gentle shepherd of souls. "It is with the Word that we must fight," said he; "by the Word must we overthrow and destroy what has been set up by violence. I will not make use of force against the superstitious and unbelieving. Let him who believeth draw nigh! let him who believeth not keep afar off! no one must be constrained. Liberty is the very essence of faith."[136] [136] Non enim ad fidem et ad ea quæ fidei sunt, ullus cogendus est......L. Epp. ii. 151. The next day was Sunday. On that day the doctor, whom for nearly a year the lofty ramparts of the Wartburg have concealed from every eye, will reappear before the people in the pulpit of the church. It was rumoured in Wittemberg that Luther was come back, that he was going to preach. This news alone, passing from mouth to mouth, had already given a powerful diversion to the ideas by which the people were misled. They are going to see the hero of Worms. The people crowded together, and were affected by various emotions. On Sunday morning the church was filled with an attentive and excited crowd.

If a man who bears a sword in his hand be alone, it is of little consequence whether it be sheathed or not; but if he is in the midst of a crowd, he should act so as to wound nobody. [Sidenote: CHARITY--THE WORD.] "What does a mother do to her infant? At first she gives it milk, then some very light food. If she were to begin by giving it meat and wine, what would be the consequence?...... "So should we act towards our brethren. My friend, have you been long enough at the breast? It is well! but permit your brother to drink as long as yourself. "Observe the sun! He dispenses two things, light and heat. There is no king so powerful as to bend aside his rays; they come straight to us; but heat is radiated and communicated in every direction. Thus faith, like light, should always be straight and inflexible; but charity, like heat, should radiate on every side, and bend to all the wants of our brethren." Luther having thus prepared his hearers, began to press them more closely:
