This is the feast, not only of all saints who have been canonized, but of all saints who have not been canonized and are in Heaven. It is, in a generous way, the feast of all those who are still on earth and are trying to be saints. No one can be a saint, without love for and protection by and devotion to the Blessed Virgin Mary. She is Queen of All Saints. She is abundantly called so in the Litany of Loreto, where she is greeted as Queen of Angels, Queen of Patriarchs, Queen of Prophets, Queen of Apostles, Queen of Martyrs, Queen of Confessors, Queen of Virgins, Queen of All Saints, Queen Conceived without Original Sin, Queen Assumed into Heaven, Queen of the Most Holy Rosary, Queen of Peace.
Saint Paul tells us, that the will of God is not merely for our salvation, but also for our sanctification. Everyone is called to be a saint. Anyone who does not become a saint has no one but himself to blame. Our Lady holds her greatest bounties and generosities in store for those who are starting to be saints.
