In any State, regardless of its non-denominational nature or the close relationship with the different religious options, it is complex to legislate in favor of the most intimate rights of all citizens, and even more to preserve a good relationship between religious confessions and the State. In our country, since the entry into force of our 1978 Constitution was for the Spanish ecclesiastical law the abandonment of the traditional confessional system that had inspired the regulation of the religious social factor throughout our constitutional history, giving way to a model deeply marked by new principles inspiring the legal regulation of relations between the Catholic Church and the Spanish State.
