8 He was accustomed to repeat to himself, as a source of inspiration, that well known phrase, "Apostles battle by their sufferings and triumph only in death." It is almost unbelievable with what vigor and constancy he defended the cause of Jesus Christ among the people of La Chablais. In order to bring them the light of faith and the comforts of the Christian religion, he was known to have traveled through deep valleys and to have climbed steep mountains. If they fled him, he pursued, calling after them loudly. Repulsed brutally, he never gave up the struggle; when threatened he only renewed his efforts. He was often put out of lodgings, at which times he passed the night asleep on the snow under the canopy of heaven. He would celebrate Mass though no one would attend. When, during a sermon, almost the entire audience one after another left the Church, he would continue preaching. At no time did he ever lose his mental poise or his spirit of kindness toward these ungrateful hearers. It was by such means as these that he finally overcame the resistance of his most formidable adversaries.
