It may be said in all truth that the Church, like Christ, goes through the centuries doing good to all. There would be today neither Socialism nor Communism if the rulers of the nations had not scorned the teachings and maternal warnings of the Church. On the bases of liberalism and laicism they wished to build other social edifices which, powerful and imposing as they seemed at first, all too soon revealed the weakness of their foundations, and today are crumbling one after another before our eyes, as everything must crumble that is not grounded on the one corner stone which is Christ Jesus.
Then, in 1955, the venerable pontiff set forth the Feast to counter the violent "May Day" demonstrations fashioned by communists, announcing instead the holy dignity of man in his labor. Pope Pius XII saw atheistic communists sabotaging the meaning of work. They decried it as demeaning to humans, crumbling that social edifice of society. This conflicts greatly with Catholic thought: work is a labor of love and union with the Divine Builder Himself. "Unless the Lord build the house, they labor in vain that build it."
