In 1955, an additional feast day was declared by Pope Pius XII and is celebrated on May 1 as the Feast of St. Joseph the Worker. Symbols associated with Joseph include the carpenter's square and lily. The carpenter's square not only symbolizes Joseph's trade but also the concept of truth.
Joseph is the patron saint of the Universal Church, families, fathers, expectant mothers, travelers, immigrants, house sellers and buyers, craftsmen, engineers, and working people, among others. Although we know Joseph as a working carpenter, he is descended from royal lineage, the line of David.
