Let us steer this prayer heavenwards without ceasing, so that God may give to the Church a publically known Pope, available to the faithful, who will renew all things in Christ:

Súpplici, Dómine, humilitáte depóscimus : ut sacrosánctæ Románæ Ecclésiæ concédat Pontificem illum tua imménsa píetas ; qui et pio in nos stúdio semper tibi plácitus, et tuo pópulo pro salúbri regímine sit assídue ad glóriam tui nóminis reveréndus. Per Dóminum nostrum Jesum Christum, Fílium tuum, qui tecum vivit et regnat in unitáte Spíritus Sancti, Deus, per ómnia sæcula sæculórum. Amen.

I only have a Dutch translation at hand here, so if anyone has the English translation, please do not hesitate to post it.

Thank you for recalling this first Votive Mass "ad diversa" from the Missal.
I have no English either, but why not use the Latin, even in private prayer?
It would be difficult to phrase this intention in a more elegant and concise way.
This reminds me of Pope Pius XII (though not a Latinist himself) who is reported to have said (can't find the source this evening): lingua Latina verba non enuntiat, sed sculpit.

One misprint: read "placitus", non "placitas".

Fixed it! Thank you.

I agree with what you say about praying in Latin.
