The story behind the feast of St. Joseph the Worker
St. Joseph is honored twice each year, on March 19 and on May 1, the latter being the feast of St. Joseph the Worker. The May 1 celebration was created by Pope Pius XII in 1955 to coincide with International Workers Day and to counter the Soviet Union’s use of the holiday to promote communism. The Pope’s intent was to preserve a Christian understanding of work and to remind workers that the Gospel informs their labor. In his 1955 address to the Catholic Association of Italian Workers, Pius XII urged that the spirit of the Gospel permeate every worker’s life.

St. Joseph is honored twice each year: on March 19 as St. Joseph, Husband of Mary, and on May 1 as St. Joseph the Worker, a feast created in 1955 to give a Christian meaning to the secular celebration of labor 1.
Pope Pius XII instituted the feast of St. Joseph the Worker on May 1, 1955 1.
He deliberately chose this date to coincide with International Workers’ Day (May Day), a holiday then used by the Soviet Union to promote communism and military might 1.
The Church has long emphasized the dignity of human work, rooted in Genesis’s command to steward the earth 1.
Pope John Paul II reinforced this in his encyclical Laborem Exercens (1981), urging the Church to defend workers’ rights and dignity 1.
Earlier, Pope Leo XIII had already highlighted St. Joseph as a model of faithful labor in his 1889 encyclical Quamquam Pluries 1.
The feast presents St. Joseph as the exemplar of a laborer who “protected and provided for his family…by his work earned what was necessary for nourishment and clothing” 1.
His life illustrates the Christian view that work is a participation in God’s creative mission.
Beyond being the patron of the universal Church, St. Joseph is also the patron saint of numerous occupations, including carpenters, engineers, accountants, lawyers, educators, and many other trades 1.
Establish how Pope Pius XII’s 1955 decree shaped Catholic labor theology
Pope Pius XII’s 1955 “decree” most notably helped shape Catholic labor theology by liturgically and pastorally fixing a theological interpretation of work: ordinary labor is not merely economic activity but part of God’s providential order, dignified through the example of St. Joseph the worker and oriented toward the worker’s good. This influence then becomes visible in later papal development of work as a matter of human dignity, rights, and a spirituality that transforms social life.
John XXIII’s account explicitly identifies Pius XII’s 1955 move: the Pope “announcing the establishment of the annual Feast of St. Joseph the Worker,” attached to May 1. The same passage notes how this institution was made in continuity with the traditional celebration of March 19 (patronage of St. Joseph).
In Catholic tradition, liturgy functions as authoritative formation: it teaches by what the Church celebrates repeatedly and publicly. By placing St. Joseph the Worker in the universal calendar on May 1, Pius XII gave workers and Christian society a recurring interpretive lens for understanding labor—not only as a social problem to manage, but as a vocation to be lived in holiness and justice.
In later papal teaching that draws on this St Joseph labor tradition, John Paul II describes the worker’s dignity in explicitly spiritual terms: Joseph “taught Jesus the carpenter’s trade,” but “above all he set him the most valuable example” of the “fear of God,” and the Pope prays for God’s blessing on “the daily work by which men and women provide bread for themselves and their loved ones,” explicitly in union with Christ, who “redeemed human work… and restored it to its original dignity.”
This is the key way Pius XII’s 1955 intervention shaped labor theology: it reinforced a “spiritual ontology” of work (work belongs within salvation-history) rather than treating labor chiefly as a technical or merely distributive problem.
Although the fullest articulation comes later, Laborem Exercens captures the continuity: the Church’s social teaching reorders economic life so that workers are treated as subjects whose dignity must not be reduced to production forces; it emphasizes just wages, solidarity, and participation in the social good.
A feast celebrating St Joseph the Worker helps ground that principle culturally: it trains believers to see the laborer as a human person with a spiritual vocation—which is precisely the anthropological basis later reflected in social encyclicals.
In a speech to the ILO’s governing body (1954), Pius XII stresses that the “human factor” needs to be placed “in the forefront,” and that the authority of such institutions depends on respect for the “high ideal animating those who press for a civilization completely open to the just aspirations of workers.” He also notes the need to safeguard “inviolable human rights contained in the natural law or formulated in positive law,” and he identifies relations between workers and employers as a particularly “touchiest spot.”
So, even before (or alongside) the 1955 liturgical decree, Pius XII’s labor theology contains a clear structure:
The 1955 feast then amplifies this structure for the faithful by giving it a living model (St Joseph) and an ongoing ecclesial rhythm (May 1).
In an Acta Apostolicae Sedis document dated May 8, 1955, Pius XII articulates a principle relevant to labor and social organization: justice and love in personal relations suffer “because one… has organized too much, and at the wrong place.” The Church’s social doctrine, the text says, requires that one should not “remove the conscience” or “personal responsibility” by “organizing them away,” and should preserve or reawaken “smaller life circles” and genuine space for people’s responsibility for common goals.
While this passage is not exclusively about workplace economics, it shapes labor theology by opposing a view of society where workers (and families) become passive recipients of systems. Instead, it supports a social order in which persons and communities retain real responsibility—an important foundation for Catholic approaches to labor rights, participation, and just governance.
John Paul II’s Laborem Exercens frames work as rooted in Genesis, essential for dignity and self-realization, and calls for reordering economic life to prioritize labor, just wages, solidarity, and the right to unionize, treating workers as subjects.
John Paul II’s Jubilee of Workers then connects that social teaching to St Joseph devotion and explicitly interprets human work as blessed when lived in the “fear of God” and in union with Christ.
Thus, the shaping effect of Pius XII’s 1955 act appears in a twofold continuity:
Pope Pius XII’s 1955 establishment of the Feast of St Joseph the Worker on May 1 shaped Catholic labor theology by embedding an authoritative ecclesial interpretation of labor: ordinary work is dignified, spiritually meaningful, and oriented toward justice and human good, grounded in St Joseph’s example and reinforced by later development of work-as-vocation in papal social teaching.
