Thanks for the insights. I feel that Our Lady as Mediatrix of all grace has been sufficiently embraced by popes, bishops, and saints down through the centuries that it cannot be ignored. That being said, the manner in which She participates in the mediation of all grace is, I think, up for debate. The Catholic faith is extremely nuanced…these are mysteries that are far beyond our current comprehension! In an earlier post on this thread I noted that, for me, it is no more difficult to accept that Our Lady is mediatrix of all grace than it is to accept that a fallible, sinful, mortal priest is mediator of all sacramental grace - for when I receive the Lord Jesus Christ from the hands of His priest, I receive all grace (Christ Himself) through the priest, yet my direct encounter with Christ is in no way diminished. As an aside, I find it ironic that the Theotokos is more prominent in the liturgical life of the East than she is in the West, but it appears that the West compensates for this with intense Marian para-liturgical devotions (eg. Rosary, Angelus). Outside of her feasts and memorials (of which, I admit, there are many), she is only mentioned a couple brief times in the daily liturgy and the only time she is directly invoked on a typical day, that I can think of, is in the final antiphon of Compline.
