The fundamental questions at stake in Thomas More’s trial continue to present themselves in ever-changing terms as new social conditions emerge. Each generation, as it seeks to advance the common good, must ask anew: what are the requirements that governments may reasonably impose upon citizens, and how far do they extend? By appeal to what authority can moral dilemmas be resolved? These questions take us directly to the ethical foundations of civil discourse. If the moral principles underpinning the democratic process are themselves determined by nothing more solid than social consensus, then the fragility of the process becomes all too evident - herein lies the real challenge for democracy.
words of Pope Benedict XVI in Westminster Hall, 2010.
