Why in marriage do they say, "till death do us part?"?

In theory, you’re allowed to re-marry after your spouse dies.

Maybe because the Christians believe in an afterlife.

In Matthew 22:30, Jesus says there is no marriage in Heaven.

^^Interesting.

That little proviso has its roots in the bible but it is not part of all religions. Islam, for instance, has no such statement during a wedding. @filmfann Has part of it. But that part was a clarification by Jesus to the Saducees about their interpretation of the Law and God’s will. Romans 7 explains the idea a bit better:

7 Do you not know, brothers and sisters—for I am speaking to those who know the law—that the law has authority over someone only as long as that person lives? 2 For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law that binds her to him. 3 So then, if she has sexual relations with another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress if she marries another man.

4 So, my brothers and sisters, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit for God. 5 For when we were in the realm of the flesh,[a] the sinful passions aroused by the law were at work in us, so that we bore fruit for death. 6 But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.

Which serves to encourage people to kill their spouses so they can remarry. ~

^^ Winner!

It’s part of a conspiracy by hair goods manufacturers.

They want you to buy combs and brushes, and then to part your hair neatly for the benefit of your spouse.

Since you won’t be doing much with your hair after you are dead, the hair equipment people came up with the expressions “until death you will part”.

because sometimes it feels like death until you part.

I used to hear jokes, the engagement ring, the wedding ring, and then the suffering.

Keep in mind people died young quite often just 150 years ago. I don’t know when those wedding vows first popped up, but women died in childbirth, men died at war, both died from infectious disease, cancers, cardiac problems, accidents, life was more treacherous in the past.

I think Meatloaf said it best:

So now I’m praying for the end of time
To hurry up and arrive
‘Cause if I gotta spend another minute with you
I don’t think that I can really survive
I’ll never break my promise or forget my vow
But God only knows what I can do right now
I’m praying for the end of time
It’s all that I can do (ooh, ooh)
Praying for the end of time
So I can end my time with you

It’s from back when people actually stayed in their marriages and worked out their differences, and it also kind of goes along with the whole, in sickness and in health, for richer or poorer, etc. The idea is that you don’t just marry somebody casually but it’s supposed to be a lifetime commitment no matter what changes.

@LifeQuestioner….well there is a reason divorce sky rocketed starting in the 70s, when women were finally afforded the opportunity to support themselves.
So yeah. People “Actually stayed together,” but in many cases it wasn’t because they wanted to. And it was no indication that people “worked their differences out.”

To answer the OP. Just another way of saying no divorce allowed.

Because “they” have a much broader vocab.

I agree with @Life_Questioner, some of us don’t believe in divorce, either via culture or religion.
It’s not that we can’t legally, we choose to stay. Good times and bad means something, its not just words. To many of us, a divorce is admitting failure or giving up on the one person we chose above all others.

@KNOWITALL Divorce, to me, is like abortion. It shouldn’t be something you do out of convenience, but there are times it is necessary. I got divorced after my ex spiraled down to where she was literally a threat to the children. There was no off ramp for her so I had to get the kids out of that environment. Divorce accomplished that. Even my brother and his family who are born again Christians and don’t believe in divorce admitted that they were glad I did it.

@seawulf575 Yes, I hate it but there are some things you can’t fix or live with. I’m not judging anyone, and maybe someday I’ll need to, but I won’t give up easily. :)

I didn’t give up either. At least not on Rick. On my first husband? Uh YA.
There was a time when it was so difficult, financially and socially, for women to get a divorce that they were almost forced to stay no matter what.
Thank God for no fault divorce.
