 Barberi's "Letter to University Professors at Oxford" describes his long hopes for the conversion of England and his belief that the men of Oxford would be instrumental in such a conversion.The letter, through the help of Ignatius Spencer, eventually ended up in the hands of Dalgairns, who was residing with John Henry Newman at Littlemore.Barberi repudiated the Anglican claim that the 39 Articles could be interpreted in a Catholic light.
