Was the Dred Scott decision biblical?

Jesuitical deception! The conservative Catholic site Patheos runs this image as Rembrandt's illustration of Paul's epistle to Philemon, but there is no such painting, and this is Bartolomé Esteban Murillo's representation of the parable of the Prodigal Son (1667-70). I call shenanigans.

Via Juan Cole, on the subject of biblical marriage:

And remember, if your sex slave runs away because you’re cruel to the person, the Bible (Philemon) says that other people have the duty to return the slave to you, i.e. basically imposes the duty of trafficking slaves back to sadistic sex maniacs who exploit them. But if the owner is nice and a good Christian, he might consider letting the sex slave go. But he doesn’t have to.

Off the subject of biblical marriage, it occurs to me that Chief Justice Taney's opinion in the Dred Scott case is biblically based: the Fugitive Slave Act is just what Paul's epistle to Philemon requires. Is that proof that the Confederate States of America were founded as a Christian nation?

Seems Frederick Douglass noticed it too:
