The men live on the street in the Rome neighbourhood just outside the Vatican's walls and were invited by the Holy See official in charge of alms-giving to attend the Mass yesterday, which Francis celebrates daily at the hotel where he lives on Vatican City grounds.
The Vatican said Francis also invited his household help to join him in a "family-like" atmosphere, and he spoke of them one by one during his homily.
After Mass, all ate breakfast with Francis at the hotel dining room.
The Vatican, which initially said four homeless people joined Francis, later clarified that three men had taken part, all from Eastern Europe: the Czech Republic, Poland and Slovakia. The Vatican newspaper L'Osservatore Romano reported that they were asked: "Would you like to come to Pope Francis' birthday party?" and that the surprise guests brought a bouquet of sunflowers to offer the pope.
Vatican officials said no fixed time was set for the papal meeting with officials and at least one player from the team, which clinched the Argentine championship on Sunday. The delegation flew from Argentina on Monday night on a private plane, to arrive in Rome yesterday.
"Arriving on such as special day, like the 77th birthday of the pope, this meeting seems made for God," said the team's vice president Marcelo Tinelli, shortly before departure.
