Eastern Orthodox churches in the U.S. have several strengths, including awe-inspiring worship, a strong sense of theological identity and a willingness to embrace new technology. But a major new study also found that in an environment that calls on all houses of worship to be more creative in reaching new generations, Eastern Orthodox parishes seem particularly resistant.

Eat, pray, read the Bible. Congregations with high levels of spiritual vitality and that placed a lot of emphasis on spiritual practices such as prayer and scripture reading were more likely to have significant numbers of young adults, according to a new report analyzing data from the 2010 Faith Communities Today study. The report provides insights into the distinctive characteristics of religious communities where 21 percent or more of participants were ages 18 to 34.

There is only one U.S. religious group, propelled in part by an enthusiastic group of young followers, that is expected to grow to 100 million adherents by the middle of the century. Yet to hear some critics focus on generational shfts showing declining Mass attendance and doctrinal commitment among white Catholics, one might think the Catholic Church is slowly sinking in the U.S. religious landscape. So which is it for the nation’s largest religious group, growth or decline? The answer is some of both, researchers say.

New research shows a sharp decline in the percentage of U.S.congreations reporting high spiritual vitality and a drop in the number of churches empasizing spiritual practices such as prayer and Scripture reading. These trends conflict with growing evidence showing the importance of congregations cultivating the spiritual lives of the faithful. The reasons for the disconnect arre varied, but it is not because religious leaders can say they don’t know any better.
