If you are not aware of the movie coming out about the story of John Newton's and William Wilberforce's Christian effort to end the slave trade called "Amazing Grace," I want to recommend it to you.
There are also some study guides for high schoolers on the movie's website at http://www.amazinggracemovie.com/. These guides focus on historical facts and are concerned about social justice in fighting against human slavery, but mention positively the influence of Christianity throughout the story that is told. They are not bible study guides, but could be of use in a Christian school. Also, there are materials for churches at the following locations:
The World Council of Churches is involved in this, which doesn't convince me that the movie's Christian message will be adequately free from hints of the "social gospel." The company that wanted the movie made wanted the story to be about the key characters' Christian faith, but compromised with the producer who wanted the story to be about the abolition of slavery. Nevertheless, if you distinguish the politics from the Christianity in the movie, this is a significant film for Christians to see.
To get the fuller story of William Wilberforce's Christian faith, you should read John Piper's short book that has just come out titled "Amazing Grace in the Life of William Wilberforce." You can even read it online here for free!
"the movie can in fact be read as anti-Presbyterian and crypto-Catholic."
Becky and I had a similar take. Except, we didn't think the Latinos were Catholic. Their worship centered around the charismatic authority of their combination shamanistic pagan witch-doctor Black Baptist preacher. The movie contrasted the two religious cultures, but also showed both religions to be false, however important for maintaining a set of shared values. The Presbyterians couldn't see the common grace in dancing, but learned to dance when threatened by the aliens when they proved to be real. The Latinos valued their charismatic leader, but in the end he was a powerless liar, a showman, who tragically misunderstood or at least miscommunicated the nature of his necklace. Perhaps it's my Scottish background, but the movie delighted in the fun of song and dance at the expense of true and false religion alike.
