Welcome to our new series: where did I get my ethics?

Does Christianity matter any more, especially now that more people than ever say they don't believe in any religion? Historian Tom Holland says that key Christian ethics have had such a profound impact on our culture that they shape the views even of modern atheists who are unaware of it. Human rights, the idea of social progress, care for the most vulnerable among us, gender equality, even ideas of secularism -- Holland and others argue that these all have to be traced back to early Christian thinking. That thinking borrowed heavily from Judaism but otherwise turned ancient value systems upside down. This series explores this provocative thesis, starting with how early Christianity related to classical Jewish thought but departed sharply from the ethics and ideas of the Greeks, Romans, and other ancient cultures.
