One of Tolkien’s sons actually
was a priest. 
Not that it would make things better though IMO: I’ll bet that a good number of those who decry Tolkien’s works as evil are the same crowd who would attack the Catholic Church as Satanic.
And here’s a letter which he sent to his son Christopher in 1944:
… Your reference to the care of your guardian angel makes me fear that ‘he’ is being specially needed. I dare say it is so. … It also reminded me of a sudden vision (or perhaps apperception which at once turned itself into pictorial form in my mind) I had not long ago when spending half an hour in St Gregory’s before the Blessed Sacrament when the Quarant’ Ore was being held there. I perceived or thought of the Light of God and in it suspended one small mote (or millions of motes to only one of which was my small mind directed), glittering white because of the individual ray from the Light which both held and lit it. (Not that there were individual rays issuing from the Light, but the mere existence of the mote and its position in relation to the Light was in itself a line, and the line was Light). And the ray was the Guardian Angel of the mote: not a thing interposed between God and the creature, but God’s very attention itself, personalized. And I do not mean ‘personified’, by a mere figure of speech according to the tendencies of human language, but a real (finite) person. Thinking of it since – for the whole thing was very immediate, and not recapturable in clumsy language, certainly not the great sense of joy that accompanied it and the realization that the shining poised mote was myself (or any other human person that I might think of with love) – it has occurred to me that (I speak diffidently and have no idea whether such a notion is legitimate: it is at any rate quite separate from the vision of the Light and the poised mote) this is a finite parallel to the Infinite. As the love of the Father and Son (who are infinite and equal) is a Person, so the love and attention of the Light to the Mote is a person (that is both with us and in Heaven): finite but divine: i.e. angelic. Anyway, dearest, I received comfort, pan of which took this curious form, which I have (I fear) failed to convey: except that I have with me now a definite awareness of you poised and shining in the Light – though your face (as all our faces) is turned from it. But we might see the glimmer in the faces (and persons as apprehended in love) of others. …
On Sunday Prisca and I cycled in wind and rain to St Gregory’s. P. was battling with a cold and other disability, and it did not do her much immediate good, though she’s better now; but we had one of Fr. C’s best sermons (and longest). A wonderful commentary on the Gospel of the Sunday (healing of the woman and of Jairus’ daughter), made intensely vivid by his comparison of the three evangelists. (P. was espec. amused by his remark that St Luke being a doctor himself did not like the suggestion that the poor woman was all the worse for them, so he toned that bit down). And also by his vivid illustrations from modern miracles. The similar case of a woman similarly afflicted (owing to a vast uterine tumour) who was cured instantly at Lourdes, so that the tumour could not be found, and her belt was twice too large. And the most moving story of the little boy with tubercular peritonitis who was
not healed, and was taken sadly away in the train by his parents, practically dying with 2 nurses attending him. As the train moved away it passed within sight of the Grotto. The little boy sat up. ‘I want to go and talk to the little girl’ – in the same train there was a little girl who had been healed. And he got up and walked there and played with the little girl; and then he came back, and he said ‘I’m hungry now’. And they gave him cake and two bowls of chocolate and enormous potted meat sandwiches, and he ate them! (This was in 1927). So Our Lord told them to give the little daughter of Jairus something to eat. So plain and matter of fact: for so miracles are. They are intrusions (as we say, erring) into real or ordinary life, but they do intrude into real life, and so need ordinary meals and other results. (Of course Fr. C could not resist adding: and there was also a Capuchin Friar who was mortally ill, & had eaten nothing for years, and he was cured, and he was so delighted about it that he rushed off and had two dinners, and that night he had not his old pains but an attack of plain ordinary indigestion).
