Propers for St. Joseph the Worker

This coming Sunday in the EF is replaced by “Saint Joseph the Worker” (1 May).

Here’s the Introit:

By the way, the Rossini Propers, published in 1933, contain the feast of St. Joseph the Workman on 1 May. I’d like to know how this was possible, since this feast wasn’t around in 1933, right? The NOH—published during the 1940s and 1950s—does not contain this feast.

UPDATE :

Audio recordings, scores, and videos for this feast have been added to the Goupil website.

English translations are in the Campion Hymnal:

Here’s how it looks in the official 1962 Missale Romanum:

Here’s how it appears in the Fulton J. Sheen Missal (which is available online as a PDF):

I’m told this feast was added by Pope Pius XII to subtly contradict communism.

Latin title: “S. Joseph Opificis”
