Bishop Schneider says the Ordinary Magisterium taught the titles “Coredemptrix” and “Mediatrix of All Graces”. Popes used them; the Vatican now calls the first always inappropriate

Mater Populi fidelis records that some popes used “Co-redemptrix” and that “Saint John Paul II referred to Mary as ‘Co-redemptrix’ on at least seven occasions”, while “the Second Vatican Council refrained from using the title for dogmatic, pastoral, and ecumenical reasons” (n. 18, text).

The same note quotes Cardinal Joseph Ratzinger’s 1996 answer to a request to define the titles: “Negative. The precise meaning of these titles is not clear, and the doctrine contained in them is not mature” (n. 19). It concludes that “it is always inappropriate to use the title ‘Co-redemptrix’ to define Mary’s cooperation” (n. 22) and that “special prudence is required when applying the term ‘Mediatrix’ to Mary” (n. 24). LifeSiteNews quotes n. 22 as “it would not be appropriate”, which is softer than the published text (Mater Populi fidelis).
