The Hymnal Worship II, published in 1975 by GIA, and widely used in the Archdiocese of Chicago, includes an English translation of Luther's German paraphrase of Psalm 46 (Vulgate No. 45) in two versions at number 2 and number 3 in the hymnal. That is the earliest attributed publication in a "Catholic" hymnal of which I am aware. I did once see a small hymnal published in an area of the country settled by people of German descent which included the text cited as "Paraphrase of Psalm 45", set to Luther's tune which was not attributed to him. I saw it in a used bookstore, but wasn't able to purchase it when I saw it; when I returned, to buy the book, it had been purchased by another buyer. I didn't take down publication details at the time, so don't know exactly who published it, when, or where.
In my view, Worship II rises to the level of "popular", but the earlier publication, which had a limited press run and distribution, does not warrant that description.
