“Christianity is a universalist and monotheist religion of salvation. Its long consolidation and explosive spread, achieved through a long period of discussion and zealous ferment, released vast human forces which have largely shaped the western world as we know it. An evolutionary and humanist religion of fulfilment could be more truly universal and could release even vaster human forces, which could in large measure shape the development of the entire world…”

Anarchism: Its Philosophy and Ideal (1896)
Context: Far be it from us not to recognize the importance of the second factor, moral teaching — especially that which is unconsciously transmitted in society and results from the whole of the ideas and comments emitted by each of us on facts and events of every-day life. But this force can only act on society under one condition, that of not being crossed by a mass of contradictory immoral teachings resulting from the practice of institutions.
In that case its influence is nil or baneful. Take Christian morality: what other teaching could have had more hold on minds than that spoken in the name of a crucified God, and could have acted with all its mystical force, all its poetry of martyrdom, its grandeur in forgiving executioners? And yet the institution was more powerful than the religion: soon Christianity — a revolt against imperial Rome — was conquered by that same Rome; it accepted its maxims, customs, and language. The Christian church accepted the Roman law as its own, and as such — allied to the State — it became in history the most furious enemy of all semi-communist institutions, to which Christianity appealed at Its origin.

"In the Storm" in Le Socialiste http://www.marxists.org/archive/luxemburg/1904/05/01.htm as translated by Mitch Abidor (1 - 8 May 1904)
Context: The Russo-Japanese War now gives to all an awareness that even war and peace in Europe – its destiny – isn’t decided between the four walls of the European concert, but outside it, in the gigantic maelstrom of world and colonial politics.
And its in this that the real meaning of the current war resides for social-democracy, even if we set aside its immediate effect: the collapse of Russian absolutism. This war brings the gaze of the international proletariat back to the great political and economic connectedness of the world, and violently dissipates in our ranks the particularism, the pettiness of ideas that form in any period of political calm.
The war completely rends all the veils which the bourgeois world – this world of economic, political and social fetishism – constantly wraps us in.
The war destroys the appearance which leads us to believe in peaceful social evolution; in the omnipotence and the untouchability of bourgeois legality; in national exclusivism; in the stability of political conditions; in the conscious direction of politics by these “statesmen” or parties; in the significance capable of shaking up the world of the squabbles in bourgeois parliaments; in parliamentarism as the so-called center of social existence.
War unleashes – at the same time as the reactionary forces of the capitalist world – the generating forces of social revolution which ferment in its depths.
