Freedom in Response: Lutheran Ethics: Sources and ControversiesThe leitmotif of Freedom in Response, as the title suggests, is a reasoned exposition of the nature of freedom, as it is presented in the Bible and developed by such later theologians as Martin Luther. Oswald Bayer considers Luther's teachings on pastoral care, marriage, and the three estates, bringing in Kant and Hegel as conversation partners, together with Kant's friend and critic, the innovative theologian and philosopher Johann Georg Hamann.
