Cardinal Gerhard Ludwig Müller defends title of Co-Redemptrix

Cardinal Gerhard Ludwig Müller defended the title of Co-Redemptrix for the Virgin Mary during an international congress at the Augustinianum Patristic Institute in Rome on October 8. Müller, the former prefect of the Dicastery for the Doctrine of the Faith, argued that the title expresses an objective truth found in revelation rather than an exaggeration.

His comments respond to a November 2025 note from the Dicastery for the Doctrine of the Faith titled Mater populi fidelis, which described the use of the title as always inopportune. Müller stated that the title should not be silenced due to objections from Protestants, but should instead be explained within the context of the work of Jesus Christ.

In his lecture, titled The Cooperation of the Blessed Virgin Mary in Redemption, Müller maintained that Mary's cooperation does not diminish the unique redemption of Christ.
