 Though the focus of the manuscript is on the homilies delivered by St. Gregory, the political message being delivered is much more open to interpretation.The parallel between the Arian and Macedonian heresy being carried out in the fourth century, and the tensions rising between the Latin and Orthodox interpretations of the Holy Spirit at the time the manuscript was created is apparent from the offset.Photios was virulently opposed to the Latin interpretation of divinity and was trying to cement the tried and tested wisdom of the eastern Orthodoxy by using the sermons of Gregory, a fellow patriarch who stood defiantly against the rule of Julian, a non-Christian emperor of the fourth century.
