I have great admiration for the LMS ORDO (LO hereafter) and often look at it. I have never found a misprint or any sort of mistake; I am myself the compiler of an ORDO and find the LMS accuracy well nigh miraculous!
So I am not criticising it; and most certainly not by snide implication. I am simply hoping to open up to the learned among my readers a question which is logically diverting but also has practical implications.
(a) LO thinks it is right to give the local calendars "as they were or should have been" on January 1 1961. I am unsure about this. Local Calendars have always tended to evolve and mutate organically. This continued to happen after 1961 just as it had before, probably by the old means of a Bishop seeking and receiving a particular grant from the SCR, until the publication of the Novus Ordo calendar in 1970, at which point, of course, the whole game-plan changed radically. Should we not incorporate such changes that appear to have happened 1961-1969? As examples, I would take the following: an ORDO of 1969 which I have (i) gives certain directions for the Christian Unity Octave in January. These mainly involve the use of the admirable Mass for the Removal of Schism. (ii) on March 17, S Patrick is shown as a Class ii feast throughout England and Wales.
Yes, I know Summorum Pontificum privileged the rite of 1962, but it did not address the inherently messy business of Local Calendars. It didn't say "local Calendars are to be held frozen at the point of evolution they had reached by 1961". After all, "1962" Missals are published nowadays which include S Joseph in the Canon, despite the fact he was added after the editio typica had been authorised and published.
(b) As LO says, a problem arises with regard to dioceses which did not exist in 1961. (i) So, e.g., Arundel and Brighton, taken out of the diocese of Southwark, is assigned by LO the Calendar of that diocese. My problem here is that the calendar concerned was not designed for Sussex. It was designed for an area including Canterbury in Kent, and so it includes (for just one example) a number of canonised Archbishops of Canterbury. These are of minimal local concern in Sussex. It also follows, of course, that the Southwark calendar, now that Sussex has left that diocese, should no longer show specifically Sussex Saints. (ii) Hallam was made up of territory taken both from Leeds and from Nottingham; and LO only allows it Feasts "which are common to both". Logically, this could be disastrous, because ... well, just suppose there were some Saint who really did belong specifically to the area included in the present diocese of Hallam ... someone who lived his Christian life there or witnessed to Christ by his death there. I don't know whether there is!! But there could be. In this case, he/she would not appear in LO as to be celebrated in Hallam unless he/she had been on the Calendars of both Leeds and Nottingham. And he/she would almost certainly not have been on both! So Hallam would lose a genuinely indigenous Saint; who would continue to be observed in another diocese which no longer embraced the area of his/her relevance!
(c) I rather wonder about those English Martyrs canonised October 25 1970 or beatified 22 November 1987. It seems a shame ... er ... I do realise that this raises questions of a different order from those in (a) and (b); particularly that of the update of the old calendar in general.
Since it is unlikely that Ecclesia Dei has the manpower or archives to sort out such problems as (a) and (b) for however many dioceses worldwide the Catholic Church has, it is, I feel, arguable that knowledgeable people should use the methodology sensibly laid out in Canon 19 and do it themselves ad interim (it could be a long interim).
I would be interested to hear of readers who happen to have English diocesan ORDOs from the years 1961,2,3,4,5,6,7,8,9.
