Newman and Henry Edward Manning both became significant figures in the late 19th-century Catholic Church in England: both were Anglican converts and both were elevated to the dignity of cardinal. In spite of these similarities, in fact there was a lack of sympathy between the two men who were different in character and experience, and they clashed on a number of issues, in particular the foundation of an Oratory in Oxford. On theological issues, Newman had reservations about the declaration of papal infallibility (Manning favoured the formal declaration of the doctrine).
