76 The State itself, mindful of its responsibility before God and society, should be a model of prudence and sobriety in the administration of the commonwealth. Today more than ever the acute world crisis demands that those who dispose of immense funds, built up on the sweat and toil of millions, keep constantly and singly in mind the common good. State functionaries and all employees are obliged in conscience to perform their duties faithfully and unselfishly, imitating the brilliant example of distinguished men of the past and of our own day, who with unremitting labor sacrificed their all for the good of their country. In international trade-relations let all means be sedulously employed for the removal of those artificial barriers to economic life which are the effects of distrust and hatred. All must remember that the peoples of the earth form but one family in God.
