Apparently in response to the “May Day” celebrations for workers sponsored by Communists, Pius XII instituted the feast of St. Joseph the Worker in 1955. But the relationship between Joseph and the cause of workers has a much longer history.
In a constantly necessary effort to keep Jesus from being removed from ordinary human life, the Church has from the beginning proudly emphasized that Jesus was a carpenter, obviously trained by Joseph in both the satisfactions and the drudgery of that vocation. Humanity is like God not only in thinking and loving, but also in creating. Whether we make a table or a cathedral, we are called to bear fruit with our hands and mind, ultimately for the building up of the Body of Christ.
In Brothers of Men, René Voillaume of the Little Brothers of Jesus speaks about ordinary work and holiness: “Now this holiness (of Jesus) became a reality in the most ordinary circumstances of life, those of word, of the family and the social life of a village, and this is an emphatic affirmation of the fact that the most obscure and humdrum human activities are entirely compatible with the perfection of the Son of God....this mystery involves the conviction that the evangelical holiness proper to a child of God is possible in the ordinary circumstances of someone who is poor and obliged to work for his living.”
