After his ordination, Father Maximilian returned to Poland in July 1919, worn by tuberculosis. Despite his poor health, he was assigned to the Franciscan friary at Cracow where the climate is fatal to tubercularsas a university professor. Not only was his body exhausted but at times his soul was harrowed by ridicule from some of his own Franciscan confreres. He had hoped on returning to interest all the friars at Cracow in his work. A good number of priests, brothers and student friars did respond to his call, but others shrugged their shoulders. They listened to him, then laughed among themselves, calling him a bore and a dreamer. One friar even found a nickname which delighted the detractors for awhile: “Marmalade.” The young priest walked very slowly, like animated marmalade, to avoid any abrupt movement that could provoke hemorrhage. Maximilian bore this mockery with patience and mildness. Faith, alone, allowed him to find in God and the Immaculata the affirmation and support that some of his confreres initially denied him.
