August 13
Saints Pontian and Hippolytus is invoked as patron of horses. Pope Saint Pontian was elected Bishop of Rome on July 21, 230, succeeding Pope Saint Urban I. His five-year pontificate is significant for two events: the formal posthumous condemnation in a Roman synod of the writings of Origen of Alexandria (which had been censured by his bishop Saint Demetrius), and the reconciliation of Hippolytus and his schismatic faction with the Catholic Church.Saint Hippolytus, born about 170, was a learned priest and theologian of the Roman Church, a disciple of Saint Irenaeus, and the author of important works in Greek, including the Apostolic Tradition (a major source for our knowledge of early third-century Roman liturgy and orders) and the Refutation of All Heresies.
