With time I've come to understand the meaning of the phrase "dreadful judge"

As our love does not start with Mary, so neither does it stop with Mary. Mary is a window through which our humanity first catches a glimpse of Divinity on earth. Or perhaps she is more like a magnifying glass; she intensifies our love of her Son and makes our prayers more bright and burning.
-Fulton Sheen, World’s First Love

Hail Mary, Full of Sorrows
#prayer favored by Pope Pius IX

Hail Mary, full of sorrows, the Crucified is with thee: tearful art thou amongst women, and tearful is the fruit of thy womb, Jesus. Holy Mary, Mother of the Crucified, grant tears to us crucifiers of thy Son, now and at the hour of our death.

Ave Maria doloribus plena, Crucifixus tecum: lacrymabilis te in mulieribus, et lacrymabilis fructus ventris tui, Jesus. Sancta Maria, Mater Crucifixi: lacrymas impertire nobis crucifixoribus Filii tui, nunc et in hora mortis nostrae.

Pope Pius IX desired this prayer to be said with contrite heart in honour of the most holy Virgin in her desolation.

Come to me, all you who labor and are burdened,
and I will give you rest.
