“The hallmark, then, of the advanced religious, nonsectarian or any other (and I graciously include in the definition of an "advanced religious," odious though the phrase is, all Christians on the great Vivekananda's terms; i. e, "See Christ, then you are a Christian; all else is talk") — the hallmark most commonly identifying this person is that he very frequently behaves like a fool, even an imbecile.”

In A Man Without a Country (2005) p. 80–81 Vonnegut makes a very similar statement:
God Bless You, Dr. Kevorkian (1999)
Context: About belief or lack of belief in an afterlife: Some of you may know that I am neither Christian nor Jewish nor Buddhist, nor a conventionally religious person of any sort.
I am a humanist, which means, in part, that I have tried to behave decently without any expectation of rewards or punishments after I'm dead. My German-American ancestors, the earliest of whom settled in our Middle West about the time of our Civil War, called themselves "Freethinkers," which is the same sort of thing. My great grandfather Clemens Vonnegut wrote, for example, "If what Jesus said was good, what can it matter whether he was God or not?"
I myself have written, "If it weren't for the message of mercy and pity in Jesus' Sermon on the Mount, I wouldn't want to be a human being. I would just as soon be a rattlesnake."

M. Aurelius Antoninus
Context: The last reflection of the Stoic philosophy that I have observed is in Simplicius' "Commentary on the Enchiridion of Epictetus." Simplicius was not a Christian, and such a man was not likely to be converted at a time when Christianity was grossly corrupted. But he was a really religious man, and he concludes his commentary with a prayer to the Deity which no Christian could improve.

Writings, The New Racism (1980)

As quoted by William Rees-Mogg in The Times [London] (4 April 2005) {not found}. Gandhi here makes reference to a statement of Jesus: “No servant can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon." (Luke 16:13); also partly quoted in Christianity in the Crosshairs: Real Life Solutions Discovered in the Line of Fire (2004, p. 74 books.google http://books.google.de/books?id=I7_5OM2VWuMC&pg=PA74) by Bill Wilson.
A variation is found in Bombay Sarvodaya Mandal & Gandhi Research Foundation's website mkgandhi.org http://www.mkgandhi.org/africaneedsgandhi/gandhi's_message_to_christians.htm. Christian missionary E. Stanley Jones, who spent much time with Gandhi in India, is said to have askedː “Mr Gandhi, though you quote the words of Christ often, why is it that you appear to so adamantly reject becoming his follower?". To this, Gandhi is said to have repliedː “Oh, I don’t reject your Christ. I love your Christ. It is just that so many of you Christians are so unlike your Christ”. Jones would write a book called " Mahatma Gandhi: An Interpretation https://archive.org/details/mahatmagandhiani000019mbp" (1948), where he included excerpts of his personal correspondance with Gandhi, but he did not include this conversation.
No further sources for Gandhi have been yet found; but a A similar quote is attributed to Bara Dadaː "Jesus is ideal and wonderful, but you Christians -- you are not like him." Source - Jones, E. Stanley. The Christ of the Indian Road, New York: The Abingdon Press,1925. (Page 114)
Disputed
Context: I like your Christ. I do not like your Christians. Your Christians are so unlike your Christ. The materialism of affluent Christian countries appears to contradict the claims of Jesus Christ that says it's not possible to worship both Mammon and God at the same time.
