As a response against the terrorist attacks in Paris in January 2015, people adapted ‘Je suis Charlie’ as a slogan to show their solidarity with the victims. In this article, while condemning the killings, I would like to examine the situation from the perspective of public theology: 1) the nature of laicite and the tension between the freedom of expression and respect for faith, 2) the problem of the marginalisation of minority religious groups in a secular public sphere, 3) the impact of the public demonstration and the creation of a platform for secular and sacred interactions. I shall incooperate in my presentation media reports, articles and interviews on the topic and also some of the scholarly discussions on laicite, on ‘interactive pluralism’ by Rowan Williams, and on the public engagement of religious communities.
