From a reader…
Can rose Vestments be worn on the Féria days of the 3rd week of Advent in both Extraordinary Form and Novus Ordo?
I haven’t seen an indication of that for the Novus Ordo in the Novus Ordo Ordo.
For the Extraordinary Form, the Usus Antiquior, I direct your attention to the Ordo put out by the great men at St. John Cantius in Chicago.
During the weekdays following Gaudete we find Lucy (red) and Ember Days (violet). However, on Monday (which has the option of O.L. of Guadalupe) and Thursday (Advent Feria) I see an indication for rose or violet, rose listed first.
So, this Ordo says “yes”. Angelus Press didn’t send me one this year.
As far as the Novus Ordo is concerned, perhaps the principle of “mutual enrichment” might apply. Also, given that rubrics were always considered withing the realm of moral theology, there is also the new interpretive principle developing in an ongoing walking together of mercy these days: struggle with it for a while and then just go ahead and do it.
