Correspondents, erudite ones, point out that the conjunction of Ss Anna and Joachim was filched by Bugnini from the Benedictine Calendar, which had the bright idea back in the time of Pius X, when it was thought good to liberate the Sunday Masses from being obscured by festivals which had previously been permanently lodged on to Sundays (S Joachim previously occupied the Sunday in the Octave of the Assumption). Incidentally, the main point I wished to make was the unfortunate placing of S Anna, who has a considerable and ancient cultus, second to S Joachim, who doesn't. Common Worship put S Anna first; whether out of deference to tradition, feminism, or both, one might wonder!
I also wonder what happens in Brittany (and in other places and churches where S Anna is Patron). Under the Novus regime are they allowed to have a special Mass and Office just of S Anna, or do they have to use the conflate Mass? Incidentally, the Benedictine Office, although forcing S Joachim to muck in with his wife, does keep some fetching old Office Hymns of S Anna. (At an early stage of the conciliar revision, Dom Lentini did propose the adoption, also from the Benedictines, of a 16th century hymn to S Anna, rather a nice one, in the style and metre of Ave Maris Stella.)
Today we have S Martha. Common Worship conjoins her with Ss Mary and Lazarus ... which I think I noticed (I can't check) is an idea from the current Benedictine Calendar. Since S Mary Magdalen has her feast; and so among Anglicans and Benedictines does S Mary the sister of Lazarus; this means that, out of the three biblical characters from which the traditional liturgical picture of S Mary Magdalen was confected, only Saint Sinful Woman is now liturgically frozen out. Unfair to Working Women (Latine meretrices), sez I.
