Pope Hilarius

Hilarius went to the Second Council of Ephesus in 449 as Pope Leo I's legate and objected when the assembly moved to condemn Flavian of Constantinople. That stand earned him the rage of Dioscurus of Alexandria, who tried to trap him in the city. He slipped out by an indirect route and made it back to Rome, later building an oratory at the Lateran dedicated to John the Evangelist in thanks for the escape. Elected bishop of Rome in 461, he spent the next seven years enforcing canon law and adjudicating jurisdictional fights among the bishops of Gaul and Spain. He died on 29 February 468.
