St. Expeditus is the patron saint invoked in emergencies. His name and the legend of his cry hodie — “today, not tomorrow” — made him the saint to whom Catholics turn when a need is pressing and a solution cannot wait.
In Catholic tradition, patron saints are holy men and women whose lives and intercession are considered especially suited to particular needs, groups, or situations. The Church's practice of invoking saints reflects the doctrine of the Communion of Saints — the belief that the faithful departed remain united with the living in the one Body of Christ and can intercede before God on our behalf. The designation of a patron saint for “Emergencies” reflects centuries of Catholic popular devotion and, in many cases, formal recognition by popes or bishops.
Primary Patron
Saint Expeditus
Feast Day
April 19
Saint Expeditus is invoked as patron of emergencies. Honored as a Roman soldier-martyr who died for the faith about the year 303 under Diocletian (feast April 19), he is associated by a popular legend with the cry hodie (“today”) against the crow’s cras (“tomorrow”), symbolizing immediate decision for Christ. For this reason he became the patron of urgent causes, expeditious solutions, and emergencies — invoked by those who need help without delay. Source: catholic.org.
