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 "Engineers" reflects centuries of Catholic popular devotion and, in many cases, formal proclamations by popes or bishops recognizing a saint's particular connection to this intention through the circumstances of their life, death, or documented miracles.

Saint Patrick is invoked as patron of engineers. Patrick was born in Roman Britain late in the fourth century, the son of a deacon named Calpurnius and grandson of a priest named Potitus. In his autobiographical Confessio, written near the end of his life, he records that at age sixteen he was captured by Irish raiders and taken as a slave to Ireland, where for six years he tended sheep and underwent a profound conversion to faith in Christ.Following a vision, he escaped to a port some two hundred miles away, returned to his family, and was eventually ordained to the priesthood.
