Wow.
I can't
remember the last time I was in a church that actually
studied God's word in anything other than topical format...delivery from the pulpit as a lecture/ sermon and skipping around hitting "bullet points" was pretty much all I saw, when I was in the churches.
No church I've ever been in has done this, except the fellowship I have with a good brother each weekend.
Count yourself blessed, my friend.
Large-group interactive Bible study?

Where are you from, again?
Again, count yourself blessed.
I've never been part of such a thing inside a building with a sign out front.
In my living room or at a local coffee shop?
Sure.
I agree.
But I can't find anyone in my area that would even bother to step out of their comfort zone and confront the very words on the page.
They all tend to trust their pastors for the correct teaching of it.
The desire to avoid controversy is what made me leave the Baptist churches I grew up in.
When I sat down in my former pastor's office some 13 years ago now ( a very caring and gentle 75 year old man that everyone loved, including me ) and we went through Romans 9...twice...we finished up, he looked at me, and said, " Keep reading Dave, keep reading."
I knew
then that it was time to go...and that was the most godly church I'd ever been in; better than the one I'd first believed on Christ in.
Given the climate, I thought it best not to make waves rather than face being thrown out over my views of Scripture.
Stopped doing that ages ago.
Nowadays I keep my distance from professing believers, rather than risk offending them.
"Heresy" is relative in my area.
One man's truth is another man's heresy, and no matter what happens, we both tend to go our separate ways.
I genuinely wish I had even
part of what you seem to be enjoying.
Perhaps someday, by God's grace, He will make me part of such a thing.
