In Switzerland, the public funding of religious groups is actually under discussion. It supports only the groups which have the legal status of public law corporations, while, in a secular state, it seems that any privilege for some Churches should be abolished, or at least reduced so as not to hinder the equality in the freedom of all religions. The book focuses on this discussion, with a comparative outlook to the Europe as a whole. It covers in particular the public funding of the religious groups in the Republic of Ticino, in which the system is very complex and the tool of the Church Tax is only a residual financing instrument.
