Italy still calls itself overwhelmingly Catholic, yet daily faith is down sharply, with 35% of Italians praying every day in 2023 compared with 50% in 2000. Even among believers, practice and belief split in striking ways, from 71% who say they believe in God to just 23% attending Mass weekly. With questions like confession, miracles, same sex marriage, and religious education all measured side by side, the country’s religious identity looks less like a single trend and more like a set of competing realities.
