Sub tuum præsídium confúgimus, sancta Dei Génetrix: nostras deprecatiónes ne despícias in necessitátibus, sed a perículis cunctis líbera nos semper, Virgo gloriósa et benedícta.
We fly to thy protection, O holy Mother of God; despise not our petitions in our necessities, but deliver us always from all dangers, O glorious and blessed Virgin.
Amen.
