Oblates of the Holy Spirit
Roman Catholic religious congregation for women

The Oblates of the Holy Spirit (Italian: Suore Oblate dello Spirito Santo; Latin: Institutum Oblatarum Spiritus Sancti; abbreviation: O.S.S.) is a religious institute of pontifical right whose members profess public vows of chastity, poverty, and obedience and follow the evangelical way of life in common. Their mission includes education of youth, catechetical and pastoral activities.
The Oblates of the Holy Spirit was founded in Lucca, Italy, in 1882, by Bl. Elena Guerra.
The sisters now have houses in Cameroon, Canada, Italy, Philippines, and Rwanda.
The Generalate of the Congregation is located in Rome, Italy. As of 31 December 2008, there were 232 sisters in 36 communities.
Pope Pius X issued a pontifical decree of coronation on 9 September 1904 granted to Mother Superior Elena Guerra to impose a diadem of stars towards their venerated image of the Blessed Virgin of the Immaculate Conception for the 50th Anniversary of the Marian Jubilee of 1904, enshrined in their monastery. This decree was signed and executed by Cardinal Casimiro Gennari, and notarized by the Secretary of the Sacred Congregation of Rites, Monsigneur Archbishop Diomede Panici.

Why this record matters
The phrase “roman Catholic religious congregation for women” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 12, 2026. The linked authority identifier is Q655989. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1882, 2008 and 1904.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
