Church sociologists insist that the share of italians attending mass at least once a month remains steady at 50 % , but a study publicised in february suggests that the true figure is lower ( 23 % in the patriarchate of venice , where the research was conducted ) 教会社会学家坚称至少每月参与一次群体活动的意大利人比例仍稳定在50 % ,但是,二月份公布的一份研究表明,真实数字很低(在进行调查的威尼斯主教区,只有23 % ) 。
