After 1956, Feast of Our Lady, Queen of Heaven.

"The Holy Spirit, Sanctifier and distributor of all graces, has chosen to act exclusively through the Immaculata. Therefore the Immaculata, as the instrument of the Holy Spirit, is the Mediatrix of All Graces won by Christ at Calvary."
Saint Maximilian Kolbe

Cardinal Mercier, allegedly a great ecumenist, was a great promoter of devotion to Our Lady Mediatrix and refounded the Abbey of Afflighem under this protection.
