This historical and theological introduction to “Von der Freiheit eines Christenmenschen” was written for the launch of the new edition in the Taylorian series of Reformation pamphlets on 30 October 2020, 500 years after it was first published. The article was written by Hannah Clemens, Theology Student at the HU Berlin and Erasmus Intern at Exeter College Chapel (Oxford) in 2019, and Dennis Clemens, Philosophy Student at the HU Berlin, and translated by Raluca Vasiu and Florence Butterfield, two Oxford Modern Languages graduates who took the early modern German period option for their finals.
