The 2017 instruction of the Congregation for the Causes of Saints on relics describes how a bishop's tribunal with medical experts examines, documents, cleans, and may treat a saint's remains at a canonical recognition, and it never mentions incorruption as a requirement or a category. The Nevers sanctuary, which displays St. Bernadette's body in the chapel of Saint-Gildard, uses the word "intact" and notes that it has rested there since 1925; the light wax coverings on her face and hands were made after the exhumations and are what visitors see.
Padre Pio's body was exhumed in 2008, displayed with a lifelike silicone mask over the face, and since 2013 has rested in the lower church of San Pio in San Giovanni Rotondo, which the shrine says was built "to better welcome the relics of the saint." The shrine does not describe the body as incorrupt. Carlo Acutis's body has rested in the Santuario della Spogliazione, the church of Santa Maria Maggiore in Assisi, since April 6, 2019, with a wax and silicone face covering; church sources said the body was found intact but not incorrupt when the tomb was opened.
Other displayed saints: St. Catherine Labouré and St. Vincent de Paul at Rue du Bac in Paris (Vincent's is a wax face over bones), St. John Vianney at Ars, St. Rita at Cascia, and St. Clare in Assisi, whose body is darkened. Rome's own Apostles' tombs hold bones, not displayed bodies. The existing page on saints' tombs and preserved remains in Europe has visiting hours.
