In the 17th century, Saint Louis de Montfort foretold the coming of an era of glory of triumph of Holy Mother Church over evil, all done by Our Lady’s intervention:
“She will work the wondrous things that will happen in the latter times; the formation and the education of the great saints who will come at the end of the world are reserved to her ... They will surpass in holiness most other saints as much as the cedars of Lebanon tower above little shrubs.
“With one hand they will give battle, overthrowing and crushing heretics and their heresies, schismatics and their schisms, idolaters and their idolatries, sinners and their wickedness. With the other hand they will build the temple of the true Solomon and the mystical city of God, namely, the Blessed Virgin, who is called by the Fathers of the Church the Temple of the true Solomon and the mystical City of God... The salvation of the world began through Mary and through her it must be accomplished.”
St. Maximilian Kolbe, also mentions the same thing:
“The Immaculate one will become Queen of the whole world and of each and every soul ... mankind will draw as close as possible to happiness on this earth, anticipating that happiness for which each of us already naturally tends; that is, that limitless happiness in God, in Paradise.”
