The abbot of Corvey at the time was Paschasius Radbertus, who also wrote De Corpore et Sanguine Domini, in which he explained that the bread and wine were changed to be equal to the actual flesh and blood of Jesus. He presented a version of his work to Charles. These opposing views did not seem to create any controversy of conflict at the time. That all happened later when others took sides on the question.
Ratramnus also wrote works such as De Praedestinatione Dei, "On the Predestination of God." In this work he denied the ideas go Gottschalk of Orbais, an itinerant Saxon theologian who visited Corvey. Gottschalk believed the predestination worked on both the saved and the damned. Ratramnus defended this idea.
One of his other works was a letter about the Cynocephali, the dog-headed men. The archbishop of Hamburg-Bremen, Saint Rimbert (c.830 - 888), while on a mission in Scandinavia, heard that there were communities of men with the heads of dogs living nearby. Rimbert's question was simple: if they were living in organized communities as he was told, were they then capable of reason and therefore of the race of Adam and suitable subjects for Christian conversion?
There was a long history of cynocephali going back to classical times, and they were usually referred to as animals. Ratramnus wrote that they were indeed human in essence though not in appearance and should be converted. (There are no stories of missionaries actually finding and communicating with any communities of dog-headed men.)
Ratramnus' most significant work on the body and blood at a later date was wrongly ascribed to someone else. When Berengar of Tours (died 1088) in a later century took up the topic, he used Ratramnus' work for his arguments, thinking it was the work of John Scotus Eriugena. John Scotus Eriugena was not an obscure person, but quite prominent, and we'll see why tomorrow.
