So the union of the Choosing Stone produced Pinkie, Maud, Limestone and Marble. I think that stone needs some fine tuning.

@Keith Mowz  
doesn’t mean you can’t. Need like a 60 second edit window I swear.

As described, its an antiquated but nice way of pairing up potential couples who apparently take a while before they’re actually hitched.
 
But that doesn’t mean you can have tons of fun pretending its a magic eight ball type dealie for comedic purposes.

Now I’m reminded how the dwarves in Dragon Age revere “The Stone”.

It also seems to me that Quartz is suggesting a betrothal within a fortnight is unusually quick for a Choosing Stone pairing.

@Mort  
Yeah we really don’t know how exactly this worked. However it does sound more like it’s some kind of blind date arranger deal rather than something saying, you two are together forever now and have no choice.

@orochijes  
Yeah, this “choosing stone” sounds suspiciously like a variant on cutie mark magic.
 
Although, for those people concerned about the “arranged marriage” aspect of this… Quart’z statement that “we were betrothed within a fortnight” makes it sound as though they took a couple of weeks to know each other and then fell in love before they declared they were marrying. So, not so much an arranged marriage as a magic rock giving a big hint that they explored, found sound, and then acted on by their own decision.

Going to say that the Bible was originally in Hebrew, Aramaic and Greek.

what if the “paring stone” is actually a pregnancy test

I like it when an arranged marriage just…works. Although this “paring stone” is probably a genuinely magical item that knows when two ponies are gonna click.

And the choosing stone decreed: “Thou shall have no rock greater than I” and from that day forth it was so.

Some real religious groups, like the Quakers, have been deliberately imitating archaic language over time with various justifications. Pinkie’s family is definitely modelled after Amish-esque traits, even though they don’t follow any specific religion.

@Allonso  

What he says about the choosing stone sort of reminds me of the matchmaker from Fiddler on the Roof.

@Marusame  

 
“We asked it about Pinkie Pie once, but all that came up was ‘Reply hazy, try again later’.”

@rdibp  
You realize that the Bible is only written like that because it was translated into that deliberately, from the Latin. From Greek. From Hebrew.

where you can get the subtitle?

Informally known as the Shipping Stone.

@RIG  
It could be depending on how much say the couples have in it. However we really have no idea how this works or heck even when they did it (Remember Earth Ponies seem to live a very long time). They could have gone to this stone on their own after not finding anyone to be with for years.

@rdibp  
More like antiquated speech. Not like the Bible has a monopoly on archaic language.

It was a magic rock 8ball, they rolled it and it said “thou shalt marry I guess”

this is depressing…

Sorry, I always have some cider with new episodes :D

Gypsy magic

There was a lot regarding to possible lore in this episode.  
Pie family’s traditions were oddly specific, yet all of them take root from the “original” traditions that Applejack was familiar with. And then there’s this “pairing stone”.
 
Would it be safe to assume that there’s a whole colony full of rockultists that worship Mother Earth as true god of Earth ponies?
