In July, the Church struck back, springing an ambush on Mr. Zapatero when he accompanied King Juan Carlos to the annual national offering at the Cathedral of Santiago de Compostela. With 52 clergymen looking on, the Archbishop of Santiago, Julian Barrio, let loose a withering denunciation, accusing Mr Zapatero of perverting the natural order.He declared that marriage was "essentially heterosexual" and that the Church had every right to interfere in national politics "in cases of people's fundamental rights, or the salvation of souls."
