The revival of religion in many parts of the world and the migration of religious cultures as part of the process of globalization have posed a serious challenge to traditional constitutional secularism. This challenge comes in the form of a political and institutional struggle against secular constitutionalism, and a two pronged assault on the very legitimacy and viability of the concept. On the one hand, constitutional secularism has been attacked as inherently hostile rather than neutral toward religion; and, on the other hand, constitutional secularism has been criticized as inevitably favouring one religion (or set of religions) over others.
