Calling Mary 'Co-redemptrix' diminishes Christ, RCs told

Calling Mary "Co-redemptrix" risks diminishing the work of Christ, Roman Catholics are being told.

The warning is given in an official RC document described as a "doctrinal note on some Marian titles regarding Mary's co-operation in the work of salvation". It has been produced by the "Dicastery for the Doctrine of the Faith", a Vatican department established in 1542 to promote religious discipline in matters of faith and doctrine.

The paper also says using the term "Mediatrix" for Mary needs "special prudence" since "the Biblical statement about Christ's exclusive mediation is conclusive".
