Although there was not always consistency in practice — given that slavery was long tolerated before being unequivocally condemned — there has been a continuous affirmation throughout history of the dignity of every human being, created in the image of God, even if it took eighteen centuries for its full incompatibility with slavery to be explicitly recognized.
