Barth: the Church must stand for social justice
The Church is witness of the fact that the Son of man came to seek and to save the lost. And this implies that—casting all false impartiality aside—the Church must concentrate first on the lower and lowest levels of human society. The poor, the socially and economically weak and threatened, will always be the object of its primary and particular concern, and it will always insist on the State’s special responsibility for these weaker members of society. That it will bestow its love on them, within the framework of its own task (as part of its service), is one thing and the most important thing; but it must not concentrate on this and neglect the other thing to which it is committed by its political responsibility: the effort to achieve such a fashioning of the law as will make it impossible for “equality before the law” to become a cloak under which strong and weak, independent and dependent, rich and poor, employers and employees, in fact receive different treatment at its hands: the weak being unduly restricted, the strong unduly protected. The Church must stand for social justice in the political sphere. And in choosing between the various socialistic possibilities (social-liberalism? co-operativism? syndicalism? free trade? moderate or radical Marxism?) it will always choose the movement from which it can expect the greatest measure of social justice (leaving all other considerations on one side).
