Not a bit surprising.
According to this news article from religionlink.org, home churches are gaining ground.
I am rather amused by one statement in there, referencing how some "...question their theology because they have no trained clergy." To which I reply "Given how so many seminaries are buying into emergent and PDL, how is seminary a guarantee against anything"? Indeed, Rick Warren went to a seminary. My conferences seminary is Bethel in Minnesota, and it's buying into the new age marketing techniques of Erwin McManus.
While I'm not against formal training for ministry, I don't see it as a requirement. The closest I've seen to an argument for requiring seminary is "Paul was in the wilderness for three years". To which I reply "...and?".
Then there is the faux argument (not in the article) that you need conferences so you can send missionaries. Uh, yeah....right. I've actually heard that one.
It seems that the reason so many are starting home churches is because they want to get back to the basics. How was it done in the first century? And I'll admit bias -- I think it should be done that way too.
And you know what? Mark my words -- this will continue as traditional churches buy into the PDL/Seeker baal worship. People will eventually see it as empty. The soul can tell the difference, you know. If you eat enough cotton candy, you learn that you are still empty.
Also, as true believers become more marginalized, we will see more of an "underground church" movement. No, I haven't "had a vision", but it is going to happen barring some mercy of our Lord Jesus Christ.
