I venture to make a constructive suggestion. In 1848 Newman published Loss and Gain; a partly autobiographical novel about the life, the currents of thought, the characteristic personages of the Oxford that he left in 1845. Of course we can (and should) go to Littlemore; how evocative it is, how welcoming the Sisters. You can venerate in nearby cases the red silk MA hood that Newman wore when celebrating the Eucharist as an Anglican, and the alb he wore at his first Eucharist in full Communion with the See of S Peter. But if it is Newman's mind you are after, this novel will be your key.
It is full of the most wonderful satire (as a satirist, Newman left Dean Swift many parasangs behind): of sweet young 'Catholic' things who think that they are discussing becoming monks and nuns when really they are falling in love with each other; of dons who use the XXXIX Articles to bully undergraduates but turn out not to know the actual text terribly well; of silly young ritualists who think that Catholicism is a matter of piscinas which will never drain an actual chalice and tabernacles which will never contain an actual Host; of the bizarre figures in the religious underworld of the day. And it contains some of Newman's most moving purple passages - not least Willis's famous eulogy of the Mass; and the description of worship in the unfinished Passionist Church.
Newman also describes the emotional hold of the Anglican Prayer Book upon those who know and love it, and its capacity to be a comfort in bad times as well as good. And the picture of the hero's father describes him as a decent, pious, generous, devout, popular, gentlemanly High Tory parson of the old school. This was Newman's tribute to all that was good and lovely in the Anglicanism which he had left; but my understanding of it is that Newman is praising, in Anglicanism, those good and wholesome things which were natural goods but which preceded the special graces which come with Catholic Faith. Newman's own father had been a banker, but he gave Charles Reding a gentlemanly clerical father who was generous to the poor and whose manners made him welcome in the greatest houses ... but whose sermons were undoctrinal.
Little known because of anti-Catholic prejudice, this book is, I am convinced, one of the greatest, most cleverly and most sharply yet beautifully written pieces of fiction produced by the nineteenth century.
