I doubt that Lewis could ever feel hatred for the Catholic Church after his adult experiences, although he makes it clear that he was taught it as a child - and that in an otherwise civilized household. I think, however, that there was an instinctive distaste such as most people will feel in the presence of, say, homosexuality; however much you respect individuals and admire the likes of Virgil and Plato, nonetheless an outright invitation to practice homosexuality would meet, even before any rational response, with an outright *yuk* reaction. I think that describes Lewis' reaction to the Church.
