The Pacelli family had a long tradition of legal training.

He founded the L’Osservatore Romano on July 20, 1860. His father Filippo Pacelli, was a solicitor (lawyer) in the Congregation of the Sacred Rota. His brother, Francesco Pacelli, a Vatican lawyer as well, was dean of the lawyers of the Rota He was also the legal advisor to Pius XI, in which role he negotiated the Lateran Treaty in 1929, bringing an end to the Roman Question.

Francesco Pacelli described in his Diario della Conciliazione details and difficulties of these negotiations from a Vatican perspective. The family's parish church in Rome was the Chiesa Nuova where the body of St. Philip Neri was under the altar in a silver casket. Neri, with his unending sense of humor and love for education, music and culture, was one of the great heroes of young Eugenio Pacelli. Eugenio served as an altar boy at Chiesa Nuova, and, after his ordination as a priest, took weekly confessions there Eugenio was the third of four children, the second son. Two days after his birth, he was baptized at the Church of Saints Celso and Giuliano by his uncle, Monsignor Giuseppe Pacelli.

In the apartment where he grew up, there was a shrine of the Madonna with a prie-dieu at which Pacelli would frequently pray.
