The history of the Southern Baptist Convention over the last 20 some years is a window into the Christian corporate church. One can see leaders have no clue about the real-time problem.
About 20 years ago Albert Mohler was a part of an insurgency revolt on contemporary theology inside SBC. Pragmatic leaders were dumped in favor of stern-face white men who “knew what Bible meant.” The denomination has been in decline ever since.
In the link, Mohler correctly reviews the statistics. In England during the last 30 years, 500 churches have been destroyed and 1000 written off. About 350 are scheduled to be written off soon–the pace is quickening.
In the U.S., between 80-90% of churches are not growing or declining. More are closing than opening. Numbers are showing decline.
The reason is simple. Sexual sin is the foundation of the faith and people are no longer sinning. Sexual sin is being replaced in Western culture with the concept of mutually consenting adults. Because a large part of the church cannot leave judgment of sexual sin behind and endorse consenting adults, it is becoming not relevant.
But to Mohler, and a large part of the faith, the problem is that the message of sexual sin needs to be shouted to new audiences. More churches need to be started (“planting” is the hip Christian word). By preaching that new churches need to be started, Mohler blames someone else for the problem he created.
A large part of the faith does not understand sin is disappearing.
