May. 23 Saturday of the Seventh Week of Easter (Vigil of Pentecost), Opt. Mem.

The Roman Martyrology commemorates St. John Baptist de Rossi (1698-1764), who was from Genoa, and studied and worked in Rome before becoming a priest there and a canon of Santa Maria in Cosmedin. He worked tirelessly for homeless women, the sick, prisoners and workers, and was a very popular confessor, being called a second Philip Neri.
