Is Mary a Principle of the Body of Christ?

William: Is Mary just can Mary, merit more congruently or is it really a different kind of merit? Kevin: I think William's question about what the title means is essential in order to make the prudential judgment about whether the title should be declared formal. In my understanding, I always think about this in terms of the body of Christ, the mystical body of Christ. The principle of the body is Christ himself, and the body is united and sustained as a living body through grace. But she still stands outside of the order as an equivocal cause of grace for the whole mystical body of Jesus.
