CHICOPEE, Mass. — For many Catholic priests across the United States, these are difficult times. Those who’ve acted honorably throughout their ministry feel they’ve lost public and parishioner support due to the scandals involving sex abuse committed by other priests. A severe shortage of priests means many of them now run parishes single-handedly. There's a heavier workload than in the past and a greater degree of isolation. And some complain of a lack of support from their bishops. One priest in Michigan says church leaders' cover-up of the abuse scandal was “utterly unchristian kind of behavior."
