I know that it's the Extraordinary Form of the Mass which was once described as 'the most beautiful thing this side of Heaven' : but I have to say that Quarant 'Ore at the London Oratory comes pretty close.
Do drop in, even if only for a few minutes, just to say a quick prayer - you know you want to, and Our Lord would be truly happy to see you : and if you can't for some reason (like you're reading this in California, and the credit card is maxed out for the month !), then please say a prayer for the Good Intentions of all those who will make a prayer there this year . . .
. . . and know that you, and everyone reading this, will be most especially in my prayers throughout the Quarant 'Ore.
