In March 1075 a famous memorandum was produced at the papal court in Rome. Headed with the words Dictatus papae (the ‘Dictation’, or perhaps ‘Theses of the Pope’), it records 27 short statements, apparently spoken by Pope Gregory VII (1073-85), concerning the privileges of the Roman Church. Among these declarations were some extraordinary assertions:

That the pope alone can depose or reinstate bishops.
That he alone may use the imperial insignia.
That he may depose emperors.
That he himself may be judged by no one.
That the Roman Church has never erred, nor, 
by the witness of Scripture, will it ever err.
That he who does not agree with the Roman Church is not held to be Catholic.
