In the Archdiocese of New Orleans, the Feast of Our Lady of Prompt Succour is still kept with great solemnity.
Clementissime Jesu, qui divitias misericordiae tuae in sinu Matris Mariae collocasti: concede propitius; ut ejus patrocinio a cunctis malis mentis et corporis liberemur. Qui vivis.
Most clement Jesus, Who hast placed the riches of Thy mercy in the bosom of Thy Mother Mary: graciously grant that, by her protection, we may be delivered from every evil of mind and of body. Who livest and reignest.
