   • c. 731 CE, Bede, Historia ecclesiastica 4.1

     Hunc offerens Hadrianus pontifici, ut episcopus ordinaretur, obtinuit; his tamen condicionibus interpositis, ut ipse eum perduceret Brittaniam, eo quod iam bis partes Galliarum diuersis ex causis adisset, et ob id maiorem huius itineris peragendi notitiam haberet, sufficiensque esset in possessione hominum propriorum; et ut ei doctrinae cooperator existens diligenter adtenderet, ne quid ille contrarium ueritati fidei, Grecorum more, in ecclesiam, cui praeesset, introduceret.

     Hadrian offered him to the pope to be ordained bishop, and prevailed; but upon these conditions, that he should conduct him into Britain, because he had already travelled through France twice upon several occasions, and was, therefore, better acquainted with the way, and was, moreover, sufficiently provided with men of his own; as also that being his fellow labourer in doctrine, he might take special care that Theodore should not, according to the custom of the Greeks, introduce anything contrary to the true faith into the church where he presided.

Inflection

Third declension.
