Stella caeli - Prayer in times of pestilence (physical and spiritual)

Stella caeli exstirpavit
Quae lactavit Dominum
Mortis pestem quam plantavit
Primus parens hominum.

The Star of Heaven that nourished the Lord
drove away the plague of death which the first
parents of man brought into the world.

Ipsa Stella nunc dignetur
Sidera compescere,
Quorum bella plebem caedunt
Dirae mortis ulcere.

May this bright Star now vouchsafe to extinguish
that foul constellation whose battles have
slain the people with the wound of death.

O gloriosa Stella Maris
A peste succurre nobis;
Audi nos, nam te Filius
Nihil negans honorat.

O most pious Star of the Sea, preserve us from
pestilence; hear us, O Lady, for Thy Son honours
Thee by denying Thee nothing.

Salva nos Jesu pro quibus
Virgo mater te orat!

Save us, O Jesus,
for whom Thy Virgin Mother supplicates Thee. 

V: Ora pro nobis, Sancta Dei Genitrix
R: Ut digni efficiamur promissionibus Christi

V: Pray for us, O Holy Mother of God.
R: That we may be made worthy of the promises of Christ.

Oremus

Let us pray

O God of mercy, God of pity, God of benign clemency,
Thou Who hast had compassion on the affliction of Thy
people, and hast said to the angel striking them, “Stop thy
hand;” for the love of this glorious Star, whose breasts
Thou didst sweetly drink as antidote for our crimes,
grant the assistance of Thy grace, that we may be safely freed
from all pestilence, and from unprovided death; and mercifully
save us from the gulf of eternal perdition: through Thee,
Lord Jesus Christ, King of Glory, who livest and reignest,
world without end.  Amen.

Totus tuus ego sum 

Et omnia mea tua sunt;

Tecum semper tutus sum:

Ad Jesum per Mariam.
