It does not mention key aspects of the reform movement such as the abolishing of the triple abuse of clerical marriage, lay investiture and simony.

The axiom "That it may be permitted to him to depose emperors" qualified the early medieval balance of power embodied in the letter Famuli vestrae pietatis of Pope Gelasius I to the Eastern Roman Emperor Anastasius (494), which outlined the separation and complementarity of spiritual and temporal powers - auctoritas (spiritual) and potestas or imperium (temporal), the former being ultimately superior to the latter - under which the West had been ruled since Merovingian times.

[4] Later medieval developments of the relationship between spiritual and secular power would come with Pope Boniface VIII, who famously formulated the image of the two swords in the papal bull Unam Sanctam (1302).

[6] In 1087 Deusdedit, a cardinal and ally of Gregory, published a collection of decretals, dedicated to Pope Victor III, that embodied the law of the Church – canon law – which he had compiled from many sources, both legitimate and false (see Pseudo-Isidore).
