Ryan Burge, here:
There is absolutely no way to gather data on that tradition, but it’s clear that it’s growing incredibly fast. ... Denominational Christianity used to be an incredibly important
cultural force in American life. Leaders in these traditions use to hold
sway over millions. Today, they are a shell of their former selves. ... The big winner? That new non-denominational church down the road that has no institutional baggage.
And here:
What may be an even bigger threat to the
SBC is the dramatic rise in nondenominational churches. When looking at
the size of every major Protestant tradition over the last 14 years, the
common thread is decline.
Baptists, Methodists, Lutherans, and Presbyterians are all a smaller
share of the population now than they were in 2008. The only exception
is nondenominational Christians. They were 7.1 percent of the total
population in 2008, but that number has risen to 8.6 percent in 2022.
One advantage of nondenominational churches is that they don’t have
institutional baggage like many denominations, including the SBC. While
people are skeptical of putting money in the offering plate and having
some of it go to a head office hundreds of miles away, in
nondenominational churches those leadership decisions are handled by
people sitting in the pews each weekend. In a time of declining trust in
institutions, nondenominationals are well-positioned, and are reaping
the benefits through rising attendance and giving.
