But there is a way in which Waugh does harmonise his Catholicism and his Britishness. He is at pains to present a picture of Catholicism which is comfortable with the English mindset. This he does partly by putting less comfortable manifestations of Catholicism upon the lips of characters from whom the author is clearly to a degree distancing himself, culturally although not theologically. "Mr Goodall was [in church on All Souls' Day], popping in and down and up and out and in again assiduously, releasing toties quoties soul after soul from Purgatory. 'Twenty-eight so far', he said. 'I always try and do fifty'". Perhaps most significantly, in Brideshead Charles Ryder says "D'you know, Bridey, if ever I felt for a moment like becoming a Catholic, I should only have to talk to you for five minutes to be cured. You manage to reduce what seem quite sensible propositions to stark nonsense." One of the intriguing aspects of Brideshead is that Waugh gives the non-Catholic characters all the best arguments against Catholicism, and, at the end, while allusively making clear that Ryder has now become a Catholic, he never gives the 'answers' to all those earlier descriptions of the case against Catholicism.
There are two very minor details which Potter seems to me to have got wrong. (1) Waugh makes it clear that the priest, working as a German spy, who tried to extract military information from Crouchback, made this attempt, not "in confession", but after Absolution, when the Sacrament is complete, and the priest is no longer bound by the Seal. A priest would hardly put "extra questions ... in confession" to a penitent with the intention of reporting the answers to the Abwehr! (2) Julia Flyte's 'marriage' to Rex Mottram was invalid; it would not have been difficult to establish that she was canonically free to marry as a Catholic. The problem was that Charles Ryder was not free to marry while his wife Celia, whom he had validly married as a non-Catholic, still lived. That is why Julia has to "give up this one thing I want so much".
