With about 1,900 parishes (i.e. local congregations) and 820,000 adherents nationwide the American Orthodox Christian Churches comprise a relatively small faith tradition within the US religious scene. Yet, they occupy a unique and rather distinct ʺnicheʺ in America's diverse religious landscape. Orthodox Christian theology, church governance, demographics and the socio-economic profile of members, as well as many aspects at the local, parish-level, church life distinguish Orthodox Churches from both Roman Catholic and various Protestant Churches.
The US Orthodox Christian Churches (represented currently by the "Assembly of the Canonical Orthodox Bishops of the United States of America") have been partners in the Faith Communities Today research network from its very inception. Since 2000, the Orthodox Churches have participated in all major Faith Communities Today studies and surveys. 580 Orthodox Christian parishes (or roughly 30% of all US Orthodox parishes) took part in the most recent 2015 survey.
In their geographic setting, Orthodox parishes are much more ʺurbanʺ and ʺsuburban" compared to Roman Catholic parishes and Protestant congregations.ʺ A majority of Orthodox parishes (59%) are situated either in or around cities with population of more than 50,000.
In terms of the demographic composition of church members, Orthodox Christian parishes are significantly ʺyoungerʺ than Roman Catholic parishes and Oldline Protestant congregations. And they are slightly younger than Evangelical/Black Protestant churches. However, overall comparisons with the entire survey show only slight age differences with the Orthodox regular participants.
The worship in Orthodox Churches can be described as ʺliturgical worship.ʺ That is, unlike most Protestant denominations, both Orthodox Christian and Roman Catholic Churches have more ʺformalizedʺ (i.e. following certain established rules and traditions) worship services. Both the Orthodox Liturgy and Catholic Mass (the main worship ritual in these churches) allow for less ʺexperimentationʺ or have fewer ʺoptions to choose fromʺ than the Sunday worship services in Protestant Churches. Compared to both Oldline and Evangelical/Black congregations, the lives of Orthodox parishes are more ʺworship centered,ʺmeaning Orthodox parishes engage less with their membership in various programs and activities outside of worship than do other traditions.
Not surprisingly, Orthodox parishes have a more distinctive ʺpersonal identityʺ than Protestant congregations. Many more Orthodox parishes than other surveyed congregations agreed with the statement ʺOur parish/congregation is quite different from other congregations in our community.ʺ At the same time, compared to both Roman Catholic churches and Protestant congregations, fewer Orthodox parishes feel that they ʺhave clear mission and purpose,ʺ are ʺspiritually vital and aliveʺ and are ʺwilling to change to meet new challenges.ʺ
Somewhat surprising, several items in the survey indicated that US Orthodox Christian parishes are more proficient and frequent users of Internet and various social media than either Oldline or Evangelical/Black Protestant congregations. When clergy were asked about their personal opinions (i.e. positive or negative) about the use of Internet and social media in parish/congregation life, 66% Orthodox priests said that ʺin today's world, parishes must use modern communication technologies as widely and as well as possible."
So based on the survey results, while some aspects of Orthodoxy in the US may not be changing, it is clear that Orthodox congregations are taking advantage of a distinctive identity and Internet communication tools to publicize what they have to offer to a young audience.
