He now wrote his promised address to the people. He bated not an inch from his standpoint, so that, even if he should for the future let the controversy rest, he might not appear to have retracted anything. He allowed a value to indulgences, but only as a recompense for the 'satisfaction' given by the sinner, and adding that it was better to do good than to purchase indulgences. He urged the duty of holding fast in Christian love and unity, and notwithstanding her faults and sins, to the Romish Church, in which St. Peter and St. Paul and hundreds of martyrs had shed their blood, and of submitting to her authority, though with reference only to external matters. Propositions going beyond what was here conceded he wished to be regarded as in no way affecting the people or the common man. They should be left, he said, to the schools of theology, and learned men might fight the matter out between them. His opponents indeed, if they had admitted what Luther declared in this address, would have had to abandon their main principles, for to them the doctrine that indulgences and Church authority meant far more than was here stated was a truth indispensable for salvation. Luther wrote his letter to the Pope on March 3, 1519. It began with expressions of the deepest personal humility, but differed significantly in the quiet firmness of its tone from his other letter of the previous year to Leo X. Quietly, but as resolutely, he repudiated all idea of retracting his principles. They had already, through the opposition raised by his enemies, been propagated far and wide, beyond all his expectations, and had sunk into the hearts of the Germans, whose knowledge and judgment were now more matured. If he let himself be forced to retract them he would give occasion to accusation and revilement against the Romish Church; for the sake of her own honour he must refuse to do so. As for his battle against indulgences, his only thought had been to prevent the Mother Church from being defiled by foreign avarice, and that the people should not be led astray, but learn to set love before indulgences.
