16.3 No religion shall have a state character. The public authorities shall take into account the religious beliefs of Spanish society and shall consequently maintain appropriate cooperation relations with the Catholic Church and other confessions.

Separation of Church and State is not complete in many European Countries. The UK is one of them, where the Monarch is the head of the Church.
