Quo vadis?

Quo vadis? (Classical Latin: [kʷoː waːdis], Ecclesiastical Latin: [kʷoː vadiːs]) is a Latin phrase meaning "Where are you going?"

The modern usage of the phrase refers to a Christian tradition regarding Saint Peter. According to the apocryphal Acts of Peter (Vercelli Acts XXXV), Peter is fleeing from likely crucifixion in Rome at the hands of the government, and along the road outside the city he meets the risen Jesus. In the Latin translation, Peter asks Jesus "Quo vadis?", to which he replies, "Romam eo iterum crucifigi" ("I am going to Rome to be crucified again"). Peter thereby gains the courage to continue his ministry and returns to the city, to eventually be martyred by being crucified upside-down. The Church of Domine Quo Vadis in Rome is built where, according to legend, the meeting between Peter and Jesus took place.
