Despite the rise of the secular state, religion remains a significant force in society. Within Christianity this encompasses a wide variety of beliefs. These range from simple assertions of theism in a cultural context to complex theologies; from liberal emphases on uncertainty and exploration to dogmatic views of divine revelation. How one ‘does’ good medical ethics depends on these perspectives. Contingently, the Christian contribution to medical ethics has been huge and constructive. Central to that contribution is a core belief in the intrinsic value of human life, respect for which we are accountable to God. Christianity continues to deserve its place ‘in the public square’ and, specifically, in medical ethical discourse.
