You can your suffering to Mary as well, and tell her that you relinquish all rights to any merit you gained through acceptance of suffering, obedience in the face of temptation, practice of virtue, etc. As the Mediatrix of Grace, Mary will distribute that merit it where needed most.
In virtue of our baptism, we may apply the satisfactory value of our good works to whomever we choose, either to ourselves or to outhers. But through the consecration, we surrender this right to Mary.
- Jason M. Brunelle, Homiletics and Pastoral Review, Oct 2010It’s an interesting subject, suffering as redemptive for other members of the Body of Christ. In the face of complaints and questions about the struggles of life, I don’t hear it spoken of much either through formally through homilies and catechesis or informally in conversation. I’m glad someone is asking about it. Is it a doctrine that we have lost to a certain extent?
