[1] Rossi served in the Sacred Consistorial Congregation in the Roman Curia from 1930 until his death and as a friar had the religious name "Raffaele of Saint Joseph".

[1] Rossi served as an investigator into the stigmata of Pio of Pietrelcina at the behest of Pope Benedict XV and reported back to him with a favourable view on the Capuchin.

One of his lecturers at the Gregorian was Cardinal Louis Billot and he made friends with Father Eugenio Pacelli - future pope.

Rossi did not wish this task and sent a letter to Cardinal del Val asking to be relieved from such a serious investigation but was required to accept the position in response.

[2] Rossi travelled to Rome from his diocese to examine the documents on the friar while assessing the accusations and praise before leaving for the Franciscan convent at San Giovanni Rotondo that June with a degree of initial scepticism.

Pope Pius XI created him as the Cardinal-Priest of Santa Prassede on 30 June 1930 in advance of Rossi's appointment as the head of the Sacred Consistorial Congregation a month after.

[2] Rossi died in Crespano del Grappa during the night on 17 September 1948 and was buried at the Santa Teresa al Corso d'Italia church.

He had moved to Crespano del Grappa the month prior due to failing health and resided with the Scalabrini Fathers.
