The Fourteen Holy Helpers are a group of saints venerated together in Roman Catholicism because their intercession was believed to be particularly effective against various diseases.
This
group of "helpers in need" originated in 14th century Rhineland, due
largely as a result of the epidemic that grew to become the Black Death, but
their veneration spread almost as quickly as the plague.
Saint
Christopher venerated by Roman Catholics and Orthodox Christians alike as a
martyr killed in the reign of a Roman Emperor, however there is some confusion
whether it was Decius or Dacian.
His
patronage concerns Bubonic plague sufferers and protects against dangers while
travelling.
The
Eastern Orthodox Church venerates Saint Christopher on May 9th however the
Roman Catholic Church feasts him on the 25th July.
