It took some time but I dug up the Latin Collect for St. Pio, Padre Pio of Pietrelcina Pio of Pietrelcina 23 Sept
Collecta
Omnípotens sempitérne Deus, qui sanctum Píum, presbýterum, crucis Fílii tui singulári grátia partícipem esse donásti, et per eius ministérium misericórdiae tuae mirabília renovásti, concéde nobis, ut, eius intercessióne, passiónibus Christi iúgiter sociáti ad resurrectiónis glóriam felíciter perducámur. Per Dóminum nostrum.
