Here's something that a pope has never had the chance to do before today: Shortly after Francis was elected, he placed a phone call to his predecessor, Benedict XVI, who has been staying at a papal retreat at Italy's Castel Gandolfo since he resigned February 28.
Benedict, 85, was the first pope to resign in hundreds of years.
News of the phone call came from the Rev. Tom Rosica, a Vatican spokesman.

We've just been given confirmation about which Francis the new pope is honoring in his choice of name.
The new pope took the name Francis in honor of St. Francis of Assisi because he is a lover of the poor, Vatican spokesman the Rev. Tom Rosica told CNN.
Also, the new pope should be known as Pope Francis, not Pope Francis I, Rosica said.
