Pope Emeritus Benedict XVI’s funeral was Thursday in Vatican City.

Soon after Benedict’s death, President Joe Biden expressed condolences over the Catholic Church’s loss.

“Jill and I join Catholics and others around the world in mourning the passing of Pope Emeritus Benedict XVI,” Biden said in a tweet.

Biden is the United States' second Catholic president. The other was John F. Kennedy.

“He'll be remembered as a renowned theologian, with a lifetime of devotion to the Church, guided by his principles and faith,” Biden continued in his tweet. “May he continue to be an inspiration to all.”

Benedict, who died on Dec. 31 at the age of 95, became the head of the Catholic Church in 2005, after John Paul II’s death. Benedict resigned in 2013, saying he felt health issues were hindering his ability to carry out his duties. The BBC reported that he was the first pope to leave office since Gregory XII resigned in 1415.

The public had the opportunity to view Benedict this week as his body was lying in state in St Peter's Basilica Monday through Wednesday. The first day of the viewing drew twice as many attendees as expected. Vatican officials had said they expected 25,000-30,000 visitors the first day, but more than 65,000 people stopped by Monday, the Associated Press reported.

Pope Francis led Thursday’s funeral, which started at 9:30 a.m. local time in St. Peter’s Square in Vatican City, CNN reported.
