It struck me recently that in our discussion of the Mass of All Souls, one potentially forgotten aspect is the public celebration of the Divine Office for that feast as well, which might be another particularly efficacious opportunity.
Of course, this is also not to exclude All Saints in a similar fashion. Indeed, I would like to tie into that fact.
Unfortunately, for so many parishes, the public celebration of the Divine Office is an all too foreign idea, but perhaps events like All Saints and All Souls might be a time, like Holy Week, that would make for a good opportunity to introduce the public, and idealy solemn, celebration of these important liturgical offices, thereby introducing the faithful to an important part of the liturgical prayer of the Church.
