A patron saint is one who is venerated as a special intercessor before God. Most patron saints have been so designated, as the result of popular devotion and long-standing custom. In many cases, the fact of existing patronal devotion is clear despite historical obscurity regarding its origin. The Church has made official designation of relatively few patron saints. The theological background of the patronage of a saint includes the dogmas of the Mystical Body of Christ and the Communion of Saints. Listed below are patron saints of occupations, professions, and saints whose intercession is generally sought out for special needs.
Can. 1186 To foster the sanctification of the people of God, the Church commends to the special and filial veneration of Christ's faithful the Blessed Mary ever-Virgin, the Mother of God, whom Christ constituted the Mother of all. The Church also promotes the true and authentic cult of the other Saints, by whose example the faithful are edified and by whose intercession they are supported.
Can. 1187 Only those servants of God may be venerated by public cult who have been numbered by ecclesiastical authority among the Saints or the Blessed.
