En lieu of a homily by me here's Austin Farrer preaching at All Souls chapel, Oxford, after World War II:
‘May they rest in peace, and may light perpetual shine upon them’ - those millions among whom our friends are lost, those millions for whom we cannot choose but pray; because prayer is a sharing in the love of the heart of God, and the love of God is earnestly set towards the salvation of his spiritual creatures, by, through and out of the fire that purifies them.
The arithmetic of death perplexes our brains. What can we do but throw ourselves upon the infinity of God? It is only to a finite mind that number is an obstacle, or multiplicity a distraction. Our mind is like a box of limited content, out of which one thing must be emptied before another can find a place. The universe of creatures is queuing for a turn of our attention, and no appreciable part of the queue will ever get a turn. But no queue forms before the throne of everlasting mercy, because the nature of an infinite mind is to be simply aware of everything that is.
Everything is simply present to an infinite mind, because it exists; or rather, exists because it is present to that making mind. And though by some process of averaging and calculation I should compute the grains of sand, it would be like the arithmetic of the departed souls, an empty sum; I could not tell them as they are told in the infinity of God’s counsels, each one separately present as what it is, and simply because it is.
The thought God gives to any of his creatures is not measured by the attention he can spare, but by the object for consideration they can supply. God is not divided; it is God, not a part of God, who applies himself to the falling sparrow, and to the crucified Lord. But there is more in the beloved Son than in the sparrow, to be observed and loved and saved by God. So every soul that has passed out of this visible world, as well as every soul remaining within it, is caught and held in the unwavering beam of divine care. And we may comfort ourselves for our own inability to tell the grains of sand, or to reckon the thousands of millions of the departed.
And yet we cannot altogether escape so; for our religion is not a simple relation of every soul separately to God, it is a mystical body in which we are all members one of another. And in this mystical body it does not suffice that every soul should be embraced by the thoughts of God; it has also to be that every soul should, in its thought, embrace the other souls. For apart from this mutual embracing, it would be unintelligible why we should pray at all, either for the living or for the departed. Such prayer is nothing but the exercising of our membership in the body of Christ. God is not content to care for us each severally, unless he can also, by his Holy Spirit in each one of us, care through and in us for all the rest. Every one of us is to be a focus of that divine life of which the attractive power holds the body together in one.
So even in the darkness and blindness of our present existence, our thought ranges abroad and spreads out towards the confines of the mystical Christ, remembering the whole Church of Christ, as well militant on earth as triumphant in heaven; invoking angels, archangels and all the spiritual host.
May they rest in peace and rise in glory,
