But Felix’s special apostolate was amongst the children of the city, with whom his childlike simplicity made him a special favourite. His method with these was to gather them together in bands and, forming circle, set them to sing canticles of his own composing, by which he taught them the beauty of a good life and the ugliness of sin. These canticles became popular and frequently, when on his rounds in quest of alms, Felix would be invited into the houses of his benefactors and asked to sing. He would seize the opportunity to bring home some spiritual truth in extemporized verse. During the famine of 1580 the directors of the city’s charities asked his superiors to place Felix at their disposal to collect alms for the starving, and he was untiring in his quest.
