Cheryl Mendelson, per Alan Jacobs, writes the following in her new book on marriage:

To write about the marriage vows … is to pick one’s way through a cultural minefield. Whether wedding vows need rethinking, updating, or, possibly, discarding is now a wide-open question. Having thought, read, and rethought, I concluded – for reasons that this book exists to lay out – that the answer is a solid no. The traditional marriage vows, though they contain phrases composed a thousand or more years ago, are a form of words that say exactly what love still wants to say.

My only amendment: substitute “because” for “though” in the final sentence.
