During the discussion about establishing a Catholic house in Oxford (see here and here) the Holy See sent one of its officials, Cardinal Reisach, to England to gather the needed information for a decision to be made. This official visited various places and persons, but did not visit Newman. The latter became indignant and resentful because he had not been invited to any meeting or had his voice on the matter heard.
In a letter to Miss Bowles, one of his confidantes, after spelling out his rancor he expressed his longings for a great change in the Church, which coincides with the general lines of the Modernist and Progressivist agenda that became a reality at Vatican II.
