Though Harriet Beecher Stowe was an abolitionist her purpose for including relgion as a major theme in Uncle Tom's cabin was not to demonstrate that slavery was evil. She also used religion to criticize other aboltionists. "Harriet Beecher Stowe was a deeply committed Christian who believed that religious faith would be a major factor in the abolition of slavery – which, of course, it was. Her most famous novel, Uncle Tom’s Cabin, repeatedly underlines the redemptive power of faith in God – from Christ-like characters who represent God’s angelic love on earth to others who desperately need that love. The novel also strongly suggests that Christianity is not meant to be legalistic. Both the stern northern abolitionists, who turn religion into a series of duties, and the southern slave owners, who use contorted interpretations of the Bible to excuse their practices, are condemned as foolish. They believe that religion is a set of laws, and the novel asserts that true faith is a pure, simple, childlike love."
Simplictically, Harriet Beecher Stowe believed that all the worlds ills, slavery included, could be cured through loving one another. All religious sects promote chaos because they tend to make it sound like you have to be a believer of their faith in order to go to heaven -therefore other sects of Christianity are pitted against each other. Harriet Beecher Stowe did not want the Bible to be interpretted differently. She just wanted everyone- regardless of race to follow the universal rule to love thy neighbor as thy self and treat them as you would like to be treated.
