The Mindset of Bible Classes in the West

I take my limited experience from Redeemer.

Many of the Redeemer classes are apparently geared towards new believers. I want to grant the benefit of the doubt. But just to be fair, if it were the case, that Sunday Bible classes are meant for non-believers/new believers, ALL/most of the classes, then I must ask...do other believers/older members need any Bible lessons anymore?

The answer expected could be: Well, we have community groups (fellowships).

My response: Many of the fellowships aren't taught to be experts. In fact, they were merely sharing, or at best, guided (printout materials) sharing/discussions. Are there no expert obligations for the faithful believers? - Don't answer, I can answer for you - you want to say "let them go enroll at seminaries, right?" Behold, the collapse of Western theology.

I think when serious professional Bible studies aren't geared toward faithful believers, it maintains or creates a proud sense of attitude towards non-believers/new comers. "We are the learned", "we are the wise Christians", "we don't study together with non/new believers".

The reason I give Redeemer the benefit of the doubt is because there are classes that many long-term believers today would fail at: Apologetics and Predestination. But if they were to dumb down these classes out of an ulterior motive (as mentioned above), then it would be pathetic.
