In European and other Western countries, it has become more prominent for Christian ethics to be marginalised in public policy as part of a secularist agenda. Despite this, opportunities remain for constructive Christian advocacy and engagement in public policy formation and wider public discourse. There is an urgent need for Christian leaders and professionals to challenge the prevailing atheistic, materialist, and secularist narrative. This session will explore the biblical mandate for Government as well as how Christians should respond when secular authorities fail to fulfil that mandate in an appropriate manner. It will critique the engagement of Evangelical Christians with the state and explore how to find the right balance between maintaining a distinctive voice and working collaboratively with the Government and within public agencies to promote the common good. Finally, it explores the boundaries for Christian professionals seeking to fulfil their vocation amid legislation and policies which conflict with Christian ethics.
