The idea of his vocation ever serves to help him over his difficulties. An instance of that marvellous elasticity of mind with which he seizes on his calling to pacify both himself and his friends, is to be found in an intimate conversation held after the “greatest of his temptations” in 1527, and recorded by Bugenhagen. After Luther had declared that he saw nothing to regret in his severity towards his foes he went on to speak, with tears in his eyes, of the sects that would spring up and which his friends would not be able to withstand. He proceeded to admit that “he was sorry if he had given scandal by his buffoonery and by his vituperation,[542] but that the cause could not be displeasing to the pious, for he loved mankind [this is Bugenhagen’s remark] too much and was an enemy to all hypocrisy.” “God had not ordained” that he, so Luther here declares, “should appear as a stern and austere figure. The world finds no sins (‘_crimina_’) wherewith to reproach me, but, because it follows its own judgment, it takes great offence at me, as I see. Possibly,” so he goes on, “God wishes to delude the blind and ungrateful world (‘_mundum stultum facere_’) so that it may perish in its contempt and never see what excellent gifts God has bestowed on me alone out of so many thousands, wherewith I am to minister unto those who are His friends. Thus the world, which refuses to acclaim the word of salvation which God sends through me, will find in me, according to the divine counsel, what offends it and is to it a stumbling-block. For this God is answerable; for I shall pray that I may never be to any a cause of scandal by my sins.” “This I learnt with wondrous joy from his own lips,” adds Bugenhagen.[543] Others will, however, find Luther’s enigmatical train of thought more difficult to understand. * * * * * The above are but a few instances of an abnormal turn of mind; of the like the present work contains others in abundance. Anyone desirous of penetrating further into the folds and windings of a mind so involved should study Luther’s letters, particularly those dating from 1517 to 1522 and from 1540 to 1546. He will there find much of the same sort, which can hardly be termed either sane or reasonable; but even the passages we have quoted suffice to reveal in him an uncanny power of self-deception such as few historic characters display. Many a great genius has betrayed psychological peculiarities, indeed it seems at times to be the fate of those endowed with eminent gifts to overstep the boundaries and to venture further than the reason and reflection of thinking men can follow.[544] That Luther carried certain mental peculiarities to their utmost limit is plain from what we have seen, nor can it be right to close one’s eyes to the fact.
