It's a wedding to remember, in more than just a chapel.
Here in St. Peter's Basilica, Pope Francis is marrying 20 couples -- even some who had already lived together and had children.
It's the Church's latest push to be more open and inclusive.
His words of advise to these newlyweds were enough to make brides tearful.
(SOUNDBITE) (Italian) POPE FRANCIS SAYING:
"A small piece of advice: it is normal that newlyweds argue, it happens and it's normal. But I advise you never to end the day without making peace, never. All it takes is a small gesture. And that is how you'll keep going forward."
His approach to the wedding contrasts with that of his predecessor, Pope Benedict, who held the traditional family as sacrosanct.
Bishops from around the world will convene in the Vatican in October for a meeting on the family, and are expected to discuss marriage, divorce and contraception.
