Marx said that religion was the opiate of the people. In the United States today, opiates are the religion of the people.

One of those leaders of what they call the social revolution has said that religion is the opiate of the people. Opium...opium...opium, yes. Let us give them opium so that they can sleep and dream.

But the Marxists think that religion is an evil, because it is anti-reason ; while reason is a good in itself, which moreover emancipates man by equipping him with the intellectual as well as technological means to determine his own destiny. Now this notion of reason and religion stems from a specifically European situation, that conditioned Marx' thought about religion. The fact that Indian Marxists have simply transposed Marx' limited view to the Indian situation is just another example of how dogmatic Marxists generally are. It also shows how utterly ignorant the Indian Leftist (and generally secularist) intelligentsia is of India's home-grown religious culture.

Communism further alleges that religion is not of divine origin but is simply a man-made tool used by the dominant class to suppress the exploited class. Marx and Engels described religion as the opiate of the people which is designed to lull them into humble submission and an acceptance of the prevailing mode of production which the dominant class desires to perpetuate. Any student of history would agree that there have been times in history when unscrupulous individuals and even misdirected religious organizations have abused the power of religion, just as all other institutions of society have been abused at various times. But it was not the abuse of religion which Marx and Engels deplored as much as the very existence of religion. They considered it a creation of the dominant class, a tool and a weapon in the hands of the oppressors. They pointed out the three-fold function of religion from their point of view: first, it teaches respect for property rights; second, it teaches the poor their duties towards the property and prerogatives of the ruling class; and third, it instills a spirit of acquiescence among the exploited poor so as to destroy their revolutionary spirit. The fallacy of these allegations is obvious to any student of Judaic-Christian teachings. The Biblical teaching of respect for property applies to rich and poor alike; it admonishes the rich to give the laborer his proper wages and to share their riches with the needy.

Religion is the opiate of the masses.

And wasn’t that a common pattern in human history! Greedy religious orders, wanting to keep power for themselves, using customs and myth and threats and murder to keep the people in line and then making them believe it was all for their own good so they wouldn’t challenge the supremacy of the priesthood. Some political thinker of a few centuries ago had nailed it exactly: “Religion is the opiate of the people.”

Religion is the opium of the poor

I’m not a Marxist, but Marx got at least one thing right: for many, religion weakens the incentive to fix both personal and societal problems.

Drugs Are the Religion of the People — The Only Hope is Dope

Religion has ever filled the mind of man with darkness, and kept him in ignorance of his real duties and true interests. It is only by dispelling the clouds and phantoms of Religion, that we shall discover Truth, Reason, and Morality. Religion diverts us from the causes of evils, and from the remedies which nature prescribes; far from curing, it only aggravates, multiplies, and perpetuates them.

Religion is like drugs, it destroys the thinking mind.

Religion used to be the opium of the people. To those suffering humiliation, pain, illness, and serfdom, religion promised the reward of an after life. But now, we are witnessing a transformation, a true opium of the people is the belief in nothingness after death, the huge solace, the huge comfort of thinking that for our betrayals, our greed, our cowardice, our murders, we are not going to be judged.

I grew up as a third-generation atheist-socialist Jew. My religious training consisted of being told that religion was the opiate of the masses.

In the Middle Ages, people still reckoned on God - the cathedrals they built make that plain. But as time went by man tried to get rid of God. Marxism is nothing else than a gigantic attempt to put God on the shelf. They have tried to replace Him by technology. Scholars, in their attempt to prove that God does not exist, have resorted to the pen. And the masses have shouted: "Religion is the opium of the people.
