In this article we propose that Habermas´ account of the role of religion in the public sphere follows the Aristotelian model of distributive justice. After presenting a way in which Aristotle´s notion of distributive justice can be used to assess participation within political debates, the text will relate such a presentation with Habermas´ discussion on the role of religion in the public sphere of a deliberative democracy. Finally, in the third part of the text, we will present some conclusions. Keywords: Justice, Religion, Habermas, Aristotle, Public Sphere.
