50 Therefore We turn again in a special way to you, Christian employers and industrialists, whose problem is often so difficult for the reason that you are saddled with the heavy heritage of an unjust economic regime whose ruinous influence has been felt through many generations. We bid you be mindful of your responsibility. It is unfortunately true that the manner of acting in certain Catholic circles has done much to shake the faith of the working-classes in the religion of Jesus Christ. These groups have refused to understand that Christian charity demands the recognition of certain rights due to the workingman, which the Church has explicitly acknowledged. What is to be thought of the action of those Catholic employers who in one place succeeded in preventing the reading of Our Encyclical Quadragesimo Anno in their local churches? Or of those Catholic industrialists who even to this day have shown themselves hostile to a labor movement that We Ourselves recommended? Is it not deplorable that the right of private property defended by the Church should so often have been used as a weapon to defraud the workingman of his just salary and his social rights?
