Dear Matthew,

if you google "Pontifical Chrismal Mass traditional' you will find many websites with lots of information.

The ritual of Oils and Chrism is not in the OHS (which was incorporated wholesale into the 1960 Missale anyhow), but in the Pontificale.  Though an older version (1845) is cited below, the rite hasn't changed much at all in recent centuries, besides its being bundled within a "Mass of the Holy Chrism" as part of the Pius XII reforms.  In any case, the below is a good start for research, since it includes Chant (though after the Typical Vatican manner, Solesmes-esque ictal markings are not present).

Take a look at page 45 and onwards (numbered as pp.605ff.): https://books.google.ca/books/reader?id=Q9YHAAAAQAAJ

[SSPX Resistance News] Chrismal Mass

Does anyone have expertise on this Mass?   It takes place on Holy Thursday morning sometime after 9:00 AM (Terce), and is quite rare because it requires a bishop.  During this Mass, the bishop consecrates the holy oils, including Holy Chrism and the Oil of the Catechumens.  I will be helping with the Gregorian Chant for this Mass in 5 weeks. The Celebrant will be Bishop Williamson. The locale is "Stella Maris Chapel" outside Houston, TX. [....]  Perhaps it's in the Holy Week ritual or something.

The ritual of Oils and Chrism is not in the OHS (which was incorporated wholesale into the 1960 Missale [Romanum] anyhow),

Officium Hebdomadae Sacrae  or somesuch?

[...]  but in the Pontificale [Romanum].  Though an older version (1845) is cited below, the rite hasn't changed much at all in recent centuries, besides its being bundled within a "Mass of the Holy Chrism" as part of the Pius XII reforms.

Thanks; I hope it helps.  Indeed, I do see:

I have no idea how many pages the subject section spans, because <books.google.*/books/reader> is typically overly effective at kicking the responsiveness of  my Internet-access PC into the weeds.

I confess having no useful knowledge to contribute on chant or choral music (altho' I might avoid being the most off-key person present if I dare to add my voice to "Pange Lingua").

I recommend that if worse comes to worse[sic] you do what Mgr. Willimason[sic] tells you to do since he is the celebrant.  Remember "Obedience before sacrifice."

Ah, yes.  A CathInfo topic that arguably wouldn't be complete without a platitude posted by poche, further bloating his postings-count

But from my involvement, a few years ago, with a different ritual that requires a bishop, I'm assuming that Matthew's goal is to assemble or produce docuмents for the more-or-less local participants in that Chrismal Mass, for practical purposes, before they can rely on having Bp. Williamson present to provide detailed guidance.  Docuмents, e.g.:
· for participants, to conduct whatever rehearsal(s) might be appropriate;
· for its congregation, to follow the "quite rare" Mass; and
· for an evaluation of whether, after distributing the assembled docuмents, various clerical & lay leaders of the Resistance ought to allow them to be kept as gifts by honored participants and members of the congregation, or retrieved to assemble a printed archive for "quite rare" Masses, rituals, or ceremonies, to make them available as needed by clerical & lay leaders of the Resistance.

Note *: Classical Latin "c&#275;na, -ae" (f.), meaning the main meal of the Romans, eaten in midafternoon[**].  But in the Vulgate, the noun appears twice in Jn. 13 (:2&4)<!-- http://drbo.org/drl/chapter/50013.htm --> as "coena" (unquantified but certainly ablative).  A dictionary of ecclesiastical or medi&aelig;val Latin might reveal more about the nonclassical inserted "o".  Perhaps being from the classical verb "co&#235;o, -&#299;re", applying its compatible meaning "to come together or assemble", but consult your local formally trained classicist.  The on-line Lewis&Short insists "c&#275;na--not coena, caena; old form caesna"[**].

Note #: Having reached 10,769 postings in C.I. to date, poche has more than 1/2 as&#160;many as the forum's owner-moderator-webmaster (20,080).  Or more than 22&#160;times as many as I&#160;do, despite my having created my account 5&#160;days earlier than the platitudinous Novus Ordo&#239;te arrived, both back in mid 2012.

But from my involvement, a few years ago, with a different ritual that requires a bishop, I'm assuming that Matthew's&#160;goal is to assemble or produce docuмents for the more-or-less local participants in that Chrismal Mass, for practical purposes, before they can rely on having Bp.&#160;Williamson present to provide detailed guidance.

The words that I quoted above are not actually words originally written by poche, contrary to what a reasonable reader might assume on returning to CathInfo after days of absence, and seeing them without quoting in the immediately previous posting by poche.  Instead, they are the words of AlligatorDicax from his previous posting in this same topic (Mar 07, 2017, 3:16 pm), so the first-person pronouns refer to A.D.

There's no just excuse for a person with more than 10,000 postings on C.I. to fail to use the C.I. quoting feature whenever any 1&#160;member (e.g., poche) posts words written by any other member (e.g., AlligatorDicax), whether for criticism, praise, or ridicule.

Now back to the topic:

But&#160; Docuмents, e.g.:&#160; [....] &#183;&#160;for an evaluation of whether, after distributing the assembled docuмents, various clerical & lay leaders of the Resistance ought to allow them to be kept as gifts by honored participants and members of the congregation, or [to be] retrieved to assemble a printed archive for "quite rare" Masses, rituals, or ceremonies, to make them available as needed by clerical & lay leaders of the Resistance.

I had not considered a bulleted list too advanced a form of presentation for C.I. readers, but it obviously confused poche.  So immediately above, I&#160;edited out the first&#160;2 bullets, leaving only&#160;1, producing a single sentence&#16;

• .

One of the purposes of the Chrismal [sic]mass is the the blessing of the holy oils to be used during the year when there is a need for the priest to give extreme unction.

Of course, that's "one"--but not all--of the Church's uses for those oils.  I'm well aware of, and thus not debating, the purpose of that Mass.  Plus the readers who were not aware of the oils' purposes when they loaded this topic would already have been educated by Matthew's summary in his original posting:

[....] this [Chrismal] Mass?&#160; It takes place on Holy Thursday [....]&#160; and is quite rare [....]&#160; During this Mass, the bishop consecrates the holy oils, including Holy Chrism and the Oil of the Catechumens.

In completing his final paragraph, poche shows that, despite presumably having native literacy in English, he needs to give additional attention in C.I. to his reading comprehension (even if that additional attention reduces the daily rate at which he inflates his C.I. postings count):

This is not just "gifts" to be kept by just anybody.&#160; It is for the priests to be used [in] baptisms, confirmations, and the last rites.

Readers should now realize, from my quote as I&#160;edited it in blue above, that my 2&#160;uses of the pronoun them refer to "Docuмents"--not "holy oils"--as what might be allowed to be "kept as gifts".

As Matthew wrote when creating this topic, the Mass is "quite rare",&#160; so consider (here's some practice with a bulleted list for extra credit):
&#183;&#160;the stature of Bp.&#160;Williamson as the senior bishop providing sacraments to the Resistance;
&#183;&#160;his advancing age; and
&#183;&#160;the possibility that such a Mass won't soon return to that Resistance site (e.g., being celebrated instead at different Resistance sites over several years, in recognition of financial support, &c.).

Then consider that the docuмents specific to that Mass might have at least sentimental appeal as gifts or mementos of that occasion for Bp.&#160;Williamson's visit.  However, depending on the costs of printing, a frugal clerical or lay leader in the Resistance might sensibly decide that they cost too much to produce to allow most of them to be used only once, then taken home as mementos by the congregation.

Note #: A sentence admittedly complicated by opening with a gerund phrase and containing clauses combined via co&#246;rdinating conjunctions, but some of my blood is German.

Does anyone have expertise on this Mass?

Matthew,

You may want to contact Louis Tofari of the Romanitas Press. I am sure he will be able to offer some help.
