The Spanish Civil War - pg. 28

Of the main difficulties which the Republic was to face,
the question of church power came to the fore barely
a fortnight after Alcala Zamora's government had taken
office in mid-April. Cardinal Segura, the archbishop of
Toledo and primate of the Catholic Church in Spain,
issued a pastoral which heaped praise on Alfonso (to
whom he owed his rapid advancement) and represented
a trumpet-blast of defiance against change in any form.
Segura was not indolent prince of the church and he may
well have pictured himself as a second Ximenez de Cisneros,
the protege of Isabella who had hhelped save the Spanish
crown for the Emperor Charles with the words 'aut Caesar,
aut nihil during the revolt of the Comuneros in 1520.
