The Vatican’s doctrine office announced Thursday it will release a document on Nov. 4 about titles of Mary that refer to her “cooperation in the work of salvation.”

Mary’s contribution to human salvation, specifically the title of “Co-Redemptrix” (“Co-Redeemer”) has been a point of theological debate for decades — with proponents calling for Mary’s role in redemption to be declared a dogma but critics saying it exaggerates her importance and could damage efforts for unity with other Christian denominations.

Cardinal Víctor Manuel Fernández, prefect of the Dicastery for the Doctrine of the Faith, will present the doctrinal note on the topic, titled “Mater Populi Fidelis” (“Faithful Mother of the People”), at the Jesuit Curia in Rome.

Fernández told journalists in July the dicastery was working on a text on “various Marian themes” but did not reveal more about its content.

Theologian Father Matteo Armando, secretary of the dicastery’s doctrine department, will also speak at the presentation Nov. 4, along with an expert consulter of the dicastery, Father Maurizio Gronchi, who teaches Christology — the Church’s teaching on the person, nature, and role of Christ — at Rome’s Pontifical Urban University.

Recent popes have held varying positions on the use of the title “Co-Redemptrix” for Mary.

In 2017, the International Marian Association submitted a request to Pope Francis for public recognition of the title of Mary as “Co-Redemptrix with Jesus the Redeemer,” one of multiple petitions sent to the Vatican in the last century.

But the pope expressed his reservations about the title on more than one occasion during his pontificate.

In his general audience address on March 24, 2021, Francis said that while Christians had always given Mary beautiful titles, it was important to remember that Christ is the only redeemer, and that Mary was entrusted to us “as a mother, not as a goddess, not as co-redeemer.”

As Cardinal Joseph Ratzinger in 2000, Pope Benedict XVI said he thought the title “Co-Redemptrix” was too far from Scripture and could cause misunderstandings about Christ’s status as redeemer — though supporters of the Marian formula felt he showed more openness to the devotion in his pontificate, despite never explicitly using the term.

St. John Paul II, instead, publicly used the word “Co-Redemptrix” at least six times during his pontificate, renewing hopes in an imminent declaration of the dogma in the 1990s.

The title can be traced back to the 10th century, when some Marian litanies included the title of Mary as Redemptrix, along with her son. The prefix of “co-” was added by the 15th century, to clarify that Mary was not the Redeemer but rather someone who uniquely cooperated in the work of redemption.

“Co-Redemptrix” received magisterial recognition only centuries later, in 1908, when the Sacred Congregation for Rites used it in a decree elevating the rank of the feast of the Seven Sorrows of Mary.

Since then, it has been referenced multiple times in Church teaching, including during the Second Vatican Council, which ultimately decided against any formal recognition of the title in the document Lumen Gentium.
