'Mary', is that 'angel of light', yes, that messenger, that 'aparition' of Romaninsm, who wants Christ's place as Mediator:
Do notice the 12 gemstone breastplate, the crown [even with the horns of the Dragon], and the 7 branch shepherds rod in her hand.
She is an actual priest [sacerdote] according to Rome:
“Marked by the priestly piety of the school of Bérulle, Pope Saint Pius X was singularly favourable to the invocation of Our Blessed Lady under the title of Virgo Sacerdos. Already in 1875, Blessed Pius IX had manifested his approval of the same title in a letter addressed to Msgr Oswald Van den Berghe, author of Marie et le Sacerdoce. Saint Pius X was pleased when an Italian translation of this work appeared.
When the Daughters of the Heart of Jesus, founded by Blessed Marie de Jésus Deluil-Martiny, asked for permission to invoke the Mother of God, in their chapels, as Maria Virgo Sacerdos, Saint Pius X wishing to extend the devotion to all the faithful, charged Cardinals Vanutelli and Vivès with composing a prayer that would make this Marian title better known. The prayer appeared, indulgenced by Pope Saint Pius X, on 9 May 1906.
O Mary, Mother of Mercy,
Mother and Daughter of Him who is the Father of mercies
and the God of all consolation (1),
Dispensatrix of all the treasures of thy Son (2),
Minister of God (3),
Mother of Christ, our High Priest,
thou who art both Offerer and Altar together, (4),
Immaculate Temple of the Word of God (5),
Teacher of the Apostles and Disciples of Christ (6),
protect the Supreme Pontiff,
intercede for us and for our priests,
that Jesus Christ the Eternal High Priest
may purify our consciences,
and that we may worthily, and with loving devotion,
approach His sacred banquet.
O Immaculate Virgin,
who not only hast given us Christ the heavenly bread
for the forgiveness of sins (7),
but
who art thyself a most acceptable sacrifice offered unto God” (8),
and the glory of priests (9),
and who, as thy most blessed servant Saint Antoninius declares,
“without receiving the Sacrament of Order,
wert full of whatsoever in dignity and grace is given by it”,
thou art therefore rightly acclaimed as “Sacerdotal Virgin” (10).
Look upon us and upon the priests of thy Son,
save us, purify us, and sanctify us,
that we may receive the ineffable treasures of the Sacraments
in a holy manner
and so deserve to obtain
the eternal salvation of our souls. Amen.
Mother of Mercy, pray for us.
Mother of Jesus Christ, the Eternal Priest, pray for us.
Queen of the Clergy, pray for us.
Mary,
Sacerdotal Virgin, pray for us.

Prayer to Mary, the Sacerdotal Virgin | Vultus Christi
“The gesture with which Christ confided his disciple to his Mother and his Mother to the disciple (16) has defined an extremely close relationship between Mary and the Church. It is the will of the Lord that a Marian note mark the physiognomy of the Church, her road, her pastoral activity; and into the spiritual life of each disciple a "Marian dimension" is infused (17).” …
… Every priest knows that Mary, because she is a mother, is the eminent formator of the priesthood, since she is the one who knows how to shape the priestly heart; the Virgin, therefore, knows and wants to protect priests from dangers, exhaustion, and discouragement: with motherly solicitude she watches over the priest so that he may grow in wisdom, age, and grace before God and before men (34). …
...Finally, Mary is the "offering Virgin." The Church has perceived in the heart of the Virgin who carried the Child to Jerusalem to present him to the Lord, a willing oblation that transcended the ordinary meaning of the rite (51). "You offer your Son, Holy Virgin, and you present to the Lord the blessed fruit of your womb. You offer the holy victim, pleasing to God, for the reconciliation of us all" (St Bernard). ...
...This union of the Mother with the Son in the work of redemption reaches its culmination at Calvary, where Christ "offered himself, immaculate, to God" (52) and where Mary was beside the cross (53) suffering deeply with her Only Son and associating herself with motherly courage to his sacrifice, adhering lovingly to the immolation of the Victim engendered by her and offering herself as well to the Eternal Father. To perpetuate throughout the centuries the Sacrifice of the Cross, the Savior instituted the Eucharistic Sacrifice, memorial of his death and resurrection, and he confided it to his Spouse, the Church... who accomplishes it in union with the Saints in Heaven and, in the first place, with the blessed Virgin, whose ardent charity and unshakable faith she imitates (54).
Therefore the Church, with this same oblationary fervor and spirit lived by Mary, continually exhorts the priest to prepare himself and celebrate the Eucharist, center and summit of his interior life and apostolate. May his priestly hands elevate the consecrated bread and wine, Body and Blood of the Lord, just as Mary offered him as a child in the Temple, and having consummated the redemption at the foot of the cross, may he return it to the Father as an expiatory offering for our sins. ...
...Priestly formation, finally, has an active dimension oriented to pastoral action. The figure of Mary, her operative presence in the life of the Church, is recognized as the soul of every apostolic or pastoral work. Her spirit of service inspires the priestly ministry as an expression of love and as a response to a received gift. The pastoral challenges of our times demand action inspired by Mary's life.” [Conference of Mons. Norberto Rivera, Archbishop, Primate of Mexico; THE BLESSED VIRGIN MARY IN THE LIFE AND MINISTRY OF THE PRIEST] -
