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.

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 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.

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

"Calvin:"It says here that 'religion is the opiate of the masses.'...what do you suppose that means?"
Television: "...it means that Karl Marx hadn't seen anything yet

Religion is the opium of the people. He believed that, that dyspeptic little joint-keeper. Yes, and music is the opium of the people. Old mount-to-the-head hadn't thought of that. And now economics is the opium of the people; along with patriotism the opium of the people in Italy and Germany. What about sexual intercourse; was that an opium of the people? Of some of the people. Of some of the best of the people. But drink was a sovereign opium of the people, oh, an excellent opium. Although some prefer the radio, another opium of the people, a cheap one he had just been using. Along with these went gambling, an opium of the people if there ever was one, one of the oldest. Ambition was another, an opium of the people along with a belief in any new form of government. What you wanted was the minimum of government, always less government. Liberty, what we believed in, now the name of a MacFadden publication. We believed in that although they had not found a new name for it yet. But what was the real one? What was the real, the actual, opium of the people? He knew it very well. It was gone just a little way around the corner in that well-lighted part of his mind that was there after two or more drinks in the evening; that he knew was there (it was not really there of course). What was it? He knew very well. What was it? Of course; bread was the opium of the people. Would he remember that and would it make sense in the daylight? Bread is the opium of the people.

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.

We also know that religion, as the Marxists have always insisted, has, too often, like an opiate, tended to put people to sleep to the reality and the need for the present struggle for peace and justice.

Religion is the opium of the poor

Sí, ya sé que uno de esos caudillos de la que llaman la revolución social ha dicho que la religión es el opio del puebo. Opio... Opio... Opio, sí. Démosle opio, y que duerma y que sueñe.

Marx was wrong--religion is not the opiate of the masses, baseball is.

If religion was "the opium of the masses," then communism was the methamphetamine of the masses.

It is not religion but revolution which is the opium of the people.
