"This book combines a religiously non-confessional approach to justice with health together with an analysis of the faith-based promotion of justice with health and focuses mainly on the time period beginning from the mid-1960s. Here "justice with health" means a particular reasonable conception of socio-political justice that includes health-related capabilities among its central components. The faith-based heritage in question is Protestant, especially Lutheran, Christianity. Drawing on some of the most prominent theories of justice from the past few decades, primarily those by John Rawls and Amartya Sen, the constructive part of the study defends a moderately structured account of reasonable justice identified through ten guidelines. Although these guidelines are first defended in terms of religiously non-confessional theories, it is argued that they could be properly supported by insights of faith as well.
