"We must not only admit into the Social-Democratic Party all those workers who still retain faith in God, we must redouble our efforts to recruit them.
We are absolutely opposed to the slightest affront to these workers' religious convictions.
We recruit them in order to educate them in the spirit of our programme, and not in order to carry on an active struggle against religion."
—Vladimir Lenin
"To die for the people is weightier than Mount Tai, but to work for the fascists and die for the exploiters and oppressors is lighter than a feather."
—Mao Zedong
"One often hears it said that the mind and the body cannot both be perfect at the same time [...] This kind of talk is absurd and applies only to those who are weak in will and feeble in action, which is generally not the case of superior men."
—Mao Zedong
"Müntzer’s political doctrine followed his revolutionary religious conceptions very closely.
His programme [...] demanded the immediate establishment of the kingdom of God, of the prophesied millennium on earth.
By the kingdom of God, Müntzer understood nothing else than a state of society without class differences, without private property, and without superimposed state powers opposed to the members of society.
All existing authorities, as far as they did not submit and join the revolution, he taught, must be overthrown, all work and all property must be shared in common."
—Friedrich Engels
"To my mind, the so-called 'socialist society' is not anything immutable. Like all other social formations, it should be conceived in a state of constant flux and change.
Its crucial difference from the present order consists naturally in production organized on the basis of common ownership by the nation of all means of production."
—Friedrich Engels
Wherever Communist revolution takes hold, systemic backwardness is eliminated post-haste. Only when the power of the people is crystallized in the form of the Communist Party can even the most backward countries achieve a reliable path to prosperity and sovereignty.
