Patroness of the United States of America
Regina angelorum, ora pro nobis! (Queen of Angels, pray for us!)
Here, from Sister M. Therese, ed., I Sing of a Maiden: The Mary Book of Verse (The Macmillan Company, 1947), is a prayer-poem by Pope Leo XIII that we can certainly use today.
Pope Leo XIII (1810-1903)
WAR CRY: TO MARY
(Ardet pugna ferox; Lucifer ipse, videns)
When warfare blusters at high Lucifer's command,
And writhing monsters fume a course from Acheron's land,
With speed of wind and wing, O loving Mother haste!
Shield for the plagued of soul, sword for the heart laid waste!
Crush with thy virgin foot these cobras of the night,
Erect thy son a tower on the Mary-height
Where he may watch the serpents leave, as stars in flight.
-- From the Latin, by Raymond F. Roseliep
