Quo vadis? (Classical Latin: [kʷoː ˈwaːdɪs], Ecclesiastical Latin: [kwo ˈvadis]) is a Latin phrase meaning "Where are you going?" It is commonly translated, quoting the KJV translation of John 13:36, as "Whither goest thou?" The phrase originates from the Christian tradition regarding Saint Peter's first words to the risen Christ during their encounter along the Appian Way. According to the apocryphal Acts of Peter (Vercelli Acts XXXV; late 2nd century AD), as Peter flees from crucifixion in Rome at the hands of the government, he meets the risen Jesus along the road outside the city.
