The Church of St. Mary in Palmis at Rome, originally was called the Church of Domine Quo Vadis. The title of this church takes its' name from a pious tradition that St. Peter one day decided to leave Rome because of the persecutions. As he was leaving the city Jesus appeared to Peter. The apostle then asked Jesus, "Where are you going" (Domine quo vadis)? To which Jesus responded, "To Rome to be crucified again!" After this courage was restored to St Peter and he returned to Rome. Has there ever been a feast celebrated in the honor of this pious legend?
Traditionally, if a Local Church has a particular title to it, it should have a feast day associated with it!
