The next supposed proof of Cyril’s opposition to the Nicene doctrine is that he has not adopted in his Lectures the phrases “of the essence (οὐσίας) of the Father,” and “of one essence (ὁμοούσιον) with the Father.”  This omission is the chief ground of the reproaches cast upon the memory of Cyril by the writers of Ecclesiastical History; for this he was described by Jerome as an Arian, and by Rufinus as a waverer, while his formal acceptance of the terms used at Nicæa is called by Socrates and Sozomen an act of repentance.  By others he was denounced as ᾽Αρειανόφρων because he had addressed his letter to Constantius as “the most religious king,” and never used the word ὁμοούσιον in his Lectures.
