Good starting point. And I agree it takes a study in itself to outline a curriculum for such a class, especially within a church. I have good organizational skills and if I set my mind to it, could probably manage, but even thinking about the task abstractly is mind boggling to me. There is just so much!! And it is all interconnected. Not only that but a lot comes from rabbit trails that can naturally occur but are important in their own right.
Someone who is really good at this Sproul---once a seminary teacher. I get so much historic and language education even from his teachings. (I have started watching some of his videos on youtube that go back as far as when he was quite a young man all the way up to the most recent before his passing.)
People could start the class as an eighteen year old and still be learning when they were eighty.
I think comparisons of the theologies such as Arminianism and Calvinism and tracking them forward through theology to see the conclusions concerning God and who He is as self revealed, would arrive at if followed through to a conclusion, would be excellent. I think follow through is what is deeply missing in many of the things Christians profess to believe.
For example in Arminianism in its free will aspect, I see in its conclusion a God completely inconsistent with how God reveals HImself from beginning to end. Of stepping back from His plan of redemption at its most crucial point, it's being applied to people through the suffering and death of Christ, and leaving the effectiveness of the cross in the hands of man who consider Him their enemy and who are enemies of God.
On the Calvinist side, those who hate this theology start with a conclusion without ever bothering to arrive at it theologically. They say it makes Him evil and unfair to choose some and not choose others. They bring in scripture saying that would make Him partial when look here in acts it says He is not partial. Even though that passage in acts has nothing to do with election but is in the midst of the evidence of God bringing salvation not only to Jews but to Gentiles also. This astonished the Jews.
So the conclusion is that the God of Calvinism is not a God they like, therefore He must be the one they like. The one who lets them choose their own destiny and be responsible for their own applying of the work of Christ to themselves.
Which one is theologically sound?
Or instead of seminary we could just start at age five and continue, teaching classes in critical thinking.
