March 1918, he was declared unfit for service and discharged completely. People who had started rebuilding their lives after the war began to see in Pio a symbol of hope. Those close to him attest that he began to manifest several spiritual gifts, including the gifts of healing, bilocation, levitation, prophecy, miracles, extraordinary abstinence from both sleep and nourishment (one account states that Padre Agostino recorded one instance in which Pio was able to subsist for at least 20 days at Verafeno on only the Holy Eucharist without any other nourishment), the ability to read hearts, the gift of tongues, the gift of conversions, and pleasant-smelling wounds. Pio increasingly became well known among the wider populace. He became a spiritual director, and developed five rules for spiritual growth: weekly confession, daily Communion, spiritual reading, meditation, and examination of conscience. Rehabilitation In 1933, Pope Pius XI ordered a reversal of the ban on Pio's public celebration of Mass, arguing, "I have not been badly disposed toward Padre Pio, but I have been badly informed." In 1934, the friar was again allowed to hear confessions. He was also given honorary permission to preach despite never having taken the exam for the preaching license.

According to Luzzatto, the bulk of the money for financing the hospital came directly from Emanuele Brunatto, a keen follower of Pio, who had made his fortune in the black market in German-occupied France. The United Nations Relief and Rehabilitation Administration (UNRRA) also contributed 250 million Italian lire. Lodovico Montini, head of Democrazia Cristiana, and his brother Giovanni Battista Montini (later Pope Paul VI) facilitated engagement by UNRRA. The hospital was initially to be named "Fiorello LaGuardia", but eventually presented as the work of Pio himself. The Casa Sollievo della Sofferenza () opened in 1956. Pio handed direct control to the Holy See. However, in order that Pio might directly supervise the project, Pope Pius
