Catherine had ample opportunity to suffer from those keenly critical instincts of the respectable which she reproved in the last group of letters. Her life was full of eager unconventionalities that drew down on her the frequent distrust of her co-religionists and fellow-townsmen. We cannot tell what special cause had excited the indignation of the loyal friends to whom the following note is written; but we may enjoy the spirit of fresh and pure humility in which Catherine gives them the difficult injunction to acquiesce in any criticism made upon her. The very matters which were later to be considered as proofs of her sanctity, were during her lifetime grounds of suspicion. Some unknown, exercised in his mind over the reports of her extraordinary abstinence, took evidently what would to-day appear the somewhat impertinent course of writing her a letter of remonstrance. Catherine's inability or reluctance to eat as much as others was one of the most interesting marvels of her life to her simple contemporaries. It is clear, that partly from the extreme mortification which according to mediaeval custom she inflicted on her flesh from childhood, her condition became at an early age thoroughly abnormal. Salads and water were practically her only diet; the curious are referred to the copious details furnished by her biographers. Meantime, the present letter shows how reasonable was her own attitude in the matter. It shows also with what gentle dignity she received criticism. The little touch at the end--"I pray you not to be light in judging, if you are not surely illumined in the sight of God"--is the only hint at a natural impulse of resentment: unless one reads, as it is tempting to do, a delicate irony in the opening portion of the letter.
