What are Stowe’s arguments against slavery?

There are many arguments that Stowe uses against the practice of slavery. I think the largest one had to do with the fact that slavery was anti-Christian. Abolitionists argued that Genesis 1:27 stated that man was created in the image of God. God could not have made a slave in his image. The whole idea of enslaving another human being was contrary to Christian ideals of love and brotherhood. Many of the sympathetic white characters in her novel ascribed to this view of Christianity.
