[ on a 14 year old child being forced to marry an 35 year old adult]

To put things in perspective - arranged marriages are worldwide the standard compared to the "free marriage" we nowadays have in western countries.
At least the Chinese, Japanese, Indians, whole Africa have arranged marriages. That's more than half of the world population already.

Even in Finland you don't need to look far back in time when arranged marriages were the standard. That was the thing not longer than about 100 years ago. Marriages were arranged, we still have a remnant of that tradition where the bride's father pays for the costs of weddings.

And when we look at the age of the brides - in Finland (evangelic lutheran church) kids get Confirmation (I hope you know the meaning) at the age of 14 to 15. When you are "Confirmed" you are legally ready for being wedded. 100 years ago it was a standard that marriages were arranged and men married 14-16 year old girls.

That's completely normal.

PS. I vouch for arranged marriages, those marriages statistically work a lot better than these modern "free marriages". A lot less divorcing and happier couples. Your family has a lot better judgment in choosing a partner for you than what you have in 3 promille drunk state at some random bar at 4am in Saturday night. That's where most of relationships start, and it's not a good start for a relationship.
