Family Is Not Always Blood Quotes: 8 Real Lines, and Where "Blood Is Thicker Than Water" Came From

Search "family is not always blood" and within a few scrolls someone will tell you that the old proverb was misquoted all along: the "real" saying, they say, is "the blood of the covenant is thicker than the water of the womb," so it meant the opposite of what your grandmother thought. It is a satisfying twist. It is also, as far as anyone has been able to show, an invention of the 1990s. No one has produced a text containing that sentence before a Messianic minister, Richard Pustelniak, published it in 1994, and neither he nor the popular phrase-book writer Albert Jack, who repeated it in 2005, cited any source for it.

So this page does two jobs. First, it sets out where "blood is thicker than water" really comes from, with dates, because the history is more interesting than the myth. Then it gives you eight family is not always blood quotes that actually say what people want the fake proverb to say: that the people who stand by you can be as much family as the people you were born to. Every line below has a book, verse, film or memoir and a year behind it. Near the end you'll find a table for matching a line to a card, toast or caption, a few short messages our editors wrote, and the questions people most often ask about the phrase.

Where "blood is thicker than water" came from

The idea is old, and it has always been about kin sticking together. The Oxford Dictionary of Proverbs traces it to a medieval German beast fable; English writers picked it up in the seventeenth century, and Scottish novelists made it famous. Here is the trail, with the earliest form of each step:

The Scott line is worth reading in place, because it shows how the proverb was really used. In volume two, chapter nine of Guy Mannering (Project Gutenberg text), a dead woman's will has just disappointed a room full of relatives, and one of them, recovering from the shock, mutters "a magnanimous declaration, which he probably was not conscious of having uttered aloud": "Weel, blude's thicker than water; she's welcome to the cheeses and the hams just the same." It is a grudging, comic moment of kinship, not a vow. Wikipedia's article on the proverb summarises the earlier entries with references to the Oxford dictionary; the Lydgate, Jenkyn and Moore texts are cited there.

Not everyone accepted the proverb. A century after Scott, a young Aldous Huxley ended a satirical poem with a toast to the British Empire that turns the saying on its head:

"For Blood, as all men know, than Water's thicker, / But water's wider, thank the Lord, than Blood." — Aldous Huxley, "Ninth Philosopher's Song," in Leda (1920)

Huxley was mocking imperial back-slapping, but the couplet has outlived its target. "Wider" is the useful word: blood binds you to a few people, and the wider water carries you to everyone else. It makes a dry, clever line for a card to a friend who crossed an ocean, or moved across the country, to be with you.

Why the "blood of the covenant" version doesn't hold up

The covenant reading claims that ancient blood-brothers, bound by a ritual of shared blood, ranked above siblings who merely shared "the water of the womb." The nineteenth-century writer H. Clay Trumbull did describe blood covenants in The Blood Covenant (second edition, 1893), and he noted an Arab saying that blood is thicker than milk. But no one has found the womb-and-covenant sentence in any older proverb collection, sermon or classical text. It doesn't appear in the Bible. The editors of the Wikipedia article even left a hidden note asking contributors not to rewrite the lead around it, because it "only appeared in recent history" and was "provided without citing any historical sources."

If you want to say that friends can be closer than kin, you don't need the myth. Writers have said it plainly for three thousand years, and the rest of this page is made of their words. (We keep a running list of other family sayings with doubtful credits on our misattributed family quotes page.)

Two ancient texts that put loyalty beside lineage

The Hebrew Bible's book of Proverbs, a collection of sayings put together over centuries, has the oldest line on this page. In the King James translation of 1611:

"A man that hath friends must shew himself friendly: and there is a friend that sticketh closer than a brother." — Proverbs 18:24, King James Version (1611)

The first half is often dropped, and it matters: friendship of that kind is something you build by being a friend. "Sticketh closer than a brother" doesn't put brothers down; it assumes brothers are close, and says a friend can be closer still. It suits a card to a best friend who has been there through a divorce, an illness or a move, and it is gentle enough to post without your actual brother taking offence.

The second line comes from a scene in the Gospel of Mark where Jesus is teaching in a crowded house and his mother and brothers arrive outside and send in for him. Someone tells him they are waiting. He answers, "Who is my mother, or my brethren?" and then looks at the people sitting around him:

"Behold my mother and my brethren! For whosoever shall do the will of God, the same is my brother, and my sister, and mother." — Mark 3:34–35, King James Version (1611)

Christians have read this for centuries as the founding text of the church as a family, which is why members of many congregations still call one another brother and sister. It is not a rejection of Mary: Christian tradition places her among the faithful too. For a church small group, a godparent, or a friend who carried you in prayer, this is the most fitting line here. If you need a faith-based alternative about blood family that ends well, our page on daughter-in-law quotes tells the story of Ruth, who chose her husband's mother over her own people.

The 1977 handbook line that started it all online

The sentence most people actually mean when they search for "family isn't always blood" comes from a short novel about a barnstorming pilot and a reluctant messiah. In Richard Bach's Illusions, the messiah, Donald Shimoda, carries a little book of sayings called the Messiah's Handbook, and the narrator opens it at random:

"The bond that links your true family is not one of blood, but of respect and joy in each other's life. Rarely do members of one family grow up under the same roof." — Richard Bach, Illusions: The Adventures of a Reluctant Messiah (1977)

Bach wrote Jonathan Livingston Seagull and Illusions for readers looking for their own path, and the second sentence is the radical one: it suggests your true family is mostly scattered, people you'll meet later. Because it names "respect and joy" rather than attacking blood relatives, it is the safest of these lines for a public caption, a Friendsgiving toast or a chosen-family wedding speech. Keep both sentences; the first alone reads like a slogan, the pair reads like a thought.

Taken in: an orphan on a farm and an alien on Kauaʻi

Fiction is full of children who find their family outside their birth family, and two of the best-loved make the point without a single speech about blood. In L. M. Montgomery's Anne of Green Gables, the elderly Cuthbert siblings wanted an orphan boy to help on the farm and were sent Anne by mistake. Years later, when Anne wishes she had been the boy they asked for so she could help him more, the shy Matthew answers:

"Well now, I'd rather have you than a dozen boys, Anne. Just mind you that—rather than a dozen boys." — Matthew Cuthbert in L. M. Montgomery, Anne of Green Gables, chapter 36 (1908)

It is one of the last things Matthew says to her; he dies in the next chapter. Adoptive parents quote it because it answers the fear every adopted or fostered child carries, that they were second choice. For an adoption-day card or a "gotcha day" post, it is hard to beat. If you're writing to a step-parent rather than an adoptive one, our stepmom quotes and messages page has lines and wording ideas for that relationship.

Ninety-four years later, Disney's Lilo & Stitch (2002, written and directed by Chris Sanders and Dean DeBlois) told the same story about a lonely Hawaiian girl raised by her older sister and the destructive little alien she adopts from a shelter, thinking he is a dog. The film's "ʻohana" speech is the famous part, but the line that makes adults cry comes near the end, when Stitch has been captured and asks to say goodbye, and the aliens want to know who these people are:

"This is my family. I found it all on my own. It's little, and broken, but still good. Yeah, still good." — Stitch in Lilo & Stitch (2002)

"Little, and broken, but still good" is a generous description of any family, blood or chosen, and it works for households that don't look like the picture on a greeting card: two siblings and a dog, a single parent and a lodger, a set of roommates who do Christmas together. It reads well under a photo; put it with a picture where nobody is quite posed.

Clan, tribe, network: a journalist's census of families

In the 1970s, when commentators were busy declaring the family dead, the journalist Jane Howard, a Life magazine staff writer from 1956 to 1972, set out to visit dozens of families of every kind, from tight nuclear households and big extended clans to new communes. Her conclusion in Families was that the family wasn't dying but changing shape, and it gave the language one of its most quoted sentences on the subject:

"Call it a clan, call it a network, call it a tribe, call it a family. Whatever you call it, whoever you are, you need one." — Jane Howard, Families (1978)

The sentence is inclusive in a way that suits mixed company: it doesn't say which kind of family is better, only that everyone needs one. Use it to open a reunion speech, a community event or a welcome note to someone who has just moved to town alone.

Biological family, logical family

Armistead Maupin's Tales of the City novels, set in a San Francisco boarding house at 28 Barbary Lane, gave readers from the 1970s onward the picture of a landlady and her tenants who become one another's family. In his 2017 memoir he finally named the idea he had been writing about for forty years:

"Sooner or later, we have to venture beyond our biological family to find our logical one, the one that actually makes sense for us. We have to, if we are to live without squandering our lives." — Armistead Maupin, Logical Family: A Memoir (2017)

Maupin grew up in Raleigh, North Carolina, and by his own account was a conservative young man who once admired Jesse Helms, his boss at a local TV station, before he came out as gay at a time when that often cost people their families. So for many LGBTQ readers "logical family" is not a metaphor but a description of who showed up. The phrase is kinder than it first sounds: "biological" and "logical" sit side by side, and nothing in the sentence says you must leave the first to find the second. It suits a Pride post, a toast at a friend's wedding where their birth family is absent, or a thank-you to the people who took you in.

Picking the right line for the moment

A "family isn't always blood" post can land as a tribute to your friends or as a public swipe at your relatives, and your relatives will read it too. Decide which you mean before you post. This table pairs each line with the situation it handles best:

If you're writing after a real break with relatives, a quote about chosen family can feel like the right reply, but it will be read as a statement. Sometimes a line about the hurt itself is more honest; our collection on when shared blood wounds is written for that situation.

Short messages you can adapt

Our editors wrote these for cards and captions; change the names and details to fit.

• "We didn't share a childhood, but we've shared everything since. Happy birthday to the sister I picked."
• "Ten Thanksgivings at this table. Same chairs, same bad jokes, same people. That's a family."
• "You didn't have to show up for us. You did, every time. Thank you for being our family."
• "Blood made some of us relatives. The last few years made all of us family."
• "Welcome home, little one. You were chosen, and you always will be."

Questions readers ask about the phrase

What is the real meaning of "blood is thicker than water"?

It means family ties are stronger than other bonds. That is how it was used from the twelfth-century German "kin-blood is not spoiled by water" to Walter Scott's "blude's thicker than water" in 1815. The reversed "blood of the covenant" version has no source older than 1994.

Can you be family without being blood related?

Yes. Adoption, marriage, step-families and long friendships all make family without shared blood, and writers from the author of Proverbs ("a friend that sticketh closer than a brother") to Armistead Maupin ("our logical one") have said so.

Who said "Family isn't always blood. It's the people in your life who want you in theirs"?

We could not find an author. The line circulates unattributed on image sites and social media, and none of the versions we checked cites a book, speech or interview. If you use it, leave it uncredited rather than guessing a name.

For a quick answer to the question in the title: the proverb never secretly meant that friends beat family. But a long line of writers, from the compilers of Proverbs to the makers of Lilo & Stitch, has said what people hope it meant, and they put their names to it.
