Who is Mary in God’s plan of redemption? Is she “Co-Redemptrix”? “Mediatrix of All Graces”? What does the Church actually teach about these titles — and why has there been renewed discussion about them?

In this special votive Mass, Fr. Jason offers clarity on the Blessed Virgin Mary’s unique role in salvation history, following the recent doctrinal note Mater Populi Fidelis. The Church affirms that Jesus Christ alone is the one true Mediator (1 Timothy 2:5) — but His unique mediation is inclusive, not exclusive. In other words, Christ invites us to share in His saving work through participation, not competition. When we intercede, when we bring others to the faith, when we cooperate with grace, we are participating in His mediation.

Mary’s cooperation is utterly unique. From her “fiat” at the Annunciation to her suffering at the foot of the Cross, she united her will entirely to her Son’s redemptive mission. As Vatican II teaches (Lumen Gentium 61), “The Blessed Virgin was the handmaid of the Lord in gaining for us the greatest of all graces — redemption and salvation.” Through her motherhood, she became the living vessel through which the Author of Grace Himself entered the world.

Yet we must be clear: Mary is not divine, not a redeemer apart from Christ. She is the Mother of the Redeemer, the Mediatrix through whom God chose to send His grace into the world — the New Eve standing beside the New Adam, the Ark of the New Covenant seen in Revelation 11–12.

As Fr. Jason reminds us, “Lex orandi, lex credendi” — as we pray, so we believe. The Church’s liturgy itself honors Mary as “the Mother of Grace” and “Mediatrix of all graces,” reflecting the faith of the centuries. Through her perfect cooperation with God’s will, she models how we, too, are called to cooperate in Christ’s saving work.
