Pope Francis gave a Valentine's Day message to couples at a rare event in St. Peter's Square in Vatican City on Friday, giving advice to young people in love thinking about marriage. Watch Pope Francis's Valentine's Day message in the video below!

CNN reports that Pope Francis gave advice on how to have a happy marriage in front of thousands of young engaged couples today in Vatican City.

Three couples were given the opportunity to ask their own questions directly to the Pope before being blessed.

A couple asked the Pontiff for advice on how to have a lasting marriage.

Francis, who is committed to lifelong celibacy as a Catholic priest, said that many people are afraid these days to make "definite decisions" and long-lasting choices, but this shouldn't deter couples from marriage, CNN reports.

"Dear engaged people, you are getting ready to grow together, to build a home, to live together for good. Do not just base it on those feelings that come and go, but on the rock of true love that comes from God," he said.

Francis also took to Twitter to encourage those who are in love to take the plunge and tie the knot: "Dear young people, don't be afraid to marry. A faithful and fruitful marriage will bring you happiness," he said on his official @Pontifex account.

Another couple asked for the Pope's advice on how to live together day to day.

"Living together is an art. It's a patient art, it's a beautiful art, it's fascinating," Francis replied.

He spoke of the need to communicate with respect and attention, "to request politely so that you enter with courtesy into the life of the other."

"Do not end any day without asking each other for forgiveness, having peace back in your house and your family," he said. "Never end a single day without being at peace with each other. This is the secret in order to preserve love."
