The patron saint of Oratino is Saint Boniface, celebrated on 14 May. The town preserves the recently restored parish church of Santa Maria Assunta, with stylistic elements spanning the 13th to 18th centuries: in the vault of the central nave, a fresco depicting the Assumption, signed and dated 1791 by the painter Ciriaco Brunetti, was rediscovered and restored.
Oratino also preserves the church of Santa Maria di Loreto, from the 18th century, which houses works and decorations by the brothers Ciriaco and Stanislao Brunetti, well-known local painters, dated 1757: during restoration works carried out by the Superintendency for Architectural Heritage of Campobasso, the remains of an earlier medieval place of worship came to light.
