In the present article, the author contextualises and reasons about the concept of inclusive laicity, which is so necessary for good coexistence in our society, where at certain times in history both the attempt to impose religion or denominationalism and the attemptto exclude it from public life and deny it as a carrier of valid values have occurred. The perspective of inclusive laicity offers an appropriate framework for the different cultural and religious traditions to be able to dialogue in order to establish a large consensus on the principles and values that should be set up based on civic dialogue among those who have something to contribute to this project. The different religious denominations, and the Catholic Church in particular, given its social importance, should heed the invitation made by the project of inclusive laicity and debate, in the public space, what values should be integrated into this Agreement for Coexistence. Today the Spanish society faces the challenge of progressing toward a new understanding of laicity capable of taking advantage of the ethical energy of religious denominations and liberating thought.
