Note 111 — Chapter VII · THEORY OF THE MEDIÆVAL EMPIRE.
Reading edition
'Quapropter universorum precibus fidelium optandum est, ut in omnem gloriam vestram extendatur imperium, ut scilicet catholica fides... veraciter in una confessione cunctorum cordibus infigatur, quatenus summi Regis donante pietate eadem sanctæ pacis et perfectæ caritatis omnes ubique regat et custodiat unitas.' Quoted by Waitz (Deutsche Verfassungsgeschichte, ii. 182) from an unprinted letter of Alcuin.
