This is the editors' preface to a special issue of Philosophia on 'Religion and Limits of Liberalism'. It begins by noting the challenges which the 'return' of religions to liberal democracies poses to the liberal commitment to respect citizens’ freedom and equality. Then, with particular reference to Rawls' theory of liberal politics, it situates the papers in relation to three different senses of liberal ‘respect’ that are challenged by contemporary religions – one understood in terms of the justification of political power, another as tolerance of diversity, and the third in terms of freedom from interference. © 2018 Springer Nature Switzerlan
