The Presbyterian Church (U.S.A.) lost 5 percent of its members and more than 100 of its churches to other denominations in 2014, matching both of those figures from each of the previous two years.
Newly released statistics by the church show a membership of 1,667,767, down 5.25 percent from 2013 and 15 percent since 2011. Some 101 churches were dismissed to other denominations, bringing to 359 the number since 2012 with a growing wave of departures.
The Presbyterian Church (U.S.A.) has well under half the 4.2 million in the mid-1960s when its two predecessor denominations were at its peak, as were several other historic Protestant denominations that have since been in numerical decline.
Many of the congregations have left to join more conservative Presbyterian bodies in reaction to liberal trends in theology and sexuality, such as the approval of the ordination non-celibate gays and lesbians in 2011. Earlier this year, the denomination also authorized same-sex weddings in its churches nationwide, and the Pittsburgh Presbytery added its assent to that move on Thursday.
While there are plenty of anecdotes of people joining Presbyterian congregations because of their progressive stances, the net result has been in the red.
The membership loss has also been compounded by the denomination's aging membership and low birth rate.
The statistical report was underscored separately by a survey by the Pew Research Center released on Tuesday that found the denomination dropping to 0.9 percent of the American population in 2014 from 1.1 percent of the population in 2007.
