I'm sure there are several here that are familiar with this devotion where the Angelic Salutation is recited as seven groups of seven for a total of 49 times, each group preceded by the Pater Noster. My question, and maybe I'm being scrupulous here, would this specific Rosary suffice in place of the traditional 5 decade Rosary or should it be done in addition to the 5 decade Rosary? I'm looking to include this in my Lenten devotions, any worthy advice is much welcomed.

What you are inquiring about is the Servite Rosary. It is a distinct devotional prayer from the Dominican Crown (what one usually means by "Rosary") just as the Franciscan Crown (Rosary of the Seven Joys of the BVM) is a distinct devotional prayer. Each has its own separate indulgences and each are of equal worth and dignity. The Eastern Churches do not have rosaries. Rather, those Chirches have the Akhathist Hymn to the BVM asa well as knotted prayer ropes upin which the Jesus Prayer is recited.

When I was a child I knew only the Franciscan Crown because I was in a thoroughly Franciscan environment. I was not exposed to a regular Dominican Rosary until I started school.

I know an SSPX chapel at which the Servite Rosary instead of the Dominican Crown prayed before Mass because the chapel is dedicated to a Servite saint.

Thanks, I didn't think anything could replace the 5/15 decade Rosary but I do think a Friday devotion such as this would be an excellent Lenten practice

I know there are quite a number of SSPX chapels dedicated to Our Mother of Sorrows but am unaware of any dedicated to a Servite saint.  Who is the saint and where is the chapel?

St. Peregrine Chapel, Richfield, OH (Cleveland)

Established originally as an independent chapel in 1982 and named in honour of St. Peregrine Laziosi, OSM. The SSPX took possession of the chapel in 1991.

Thank you for sharing! I do love this devotion!
