Satisfy our just desires

"Lord our God, we humbly ask you, that, through the working of this mystery, our offences may be cleansed and our just desires fulfilled.  Through."

"Domine Deus noster, suppliciter te rogamus, ut, huius operatione mysterii, vitia nostra purgentur, et iusta desideria compleantur.  Per."

     Post-communion, Second Sunday after the Nativity, Roman missal.  This derives from the 8th century Old Gelasian.  See Corpus orationum no. 5708, on p. 84 of vol. 9

Suppliciter te rogamus, domine deus noster, ut huius operatione mysterii et vitia nostra purgentur et iusta desideria compleantur.

and Bruylants no. 813, on p. 230 of vol. 2:

Per hujus, Domine, operationem mysterii, et vitia nostra purgentur, et justa desideria compleantur.  Per.

     Cf. James 4:3:  "You ask and do not receive, because you ask wrongly [(male)], to spend it on your passions [(concupiscentiis)]."  Also Jn 8:44:  "You are of your father the devil, and your will is to do your father’s desires [(desideria)]."  Most importantly, Ps 37:4:  "Take delight in the Lord, and he will give you the desires [(petitiones)] of your heart."  Etc.
