(CNN) – Pope Francis marked his 77th birthday on Tuesday by welcoming four homeless men to a Mass and a meal at the Vatican, according to Catholic officials.
The Pope wanted a "family" environment, with just a few top aides, the staff of Casa Santa Marta – the Vatican guesthouse – and the homeless men, one of whom brought his dog, the Vatican said.
Afterward, the group sang "Happy Birthday" to Francis, and he invited everyone to eat breakfast with him at the hotel's dining room, according to the Vatican.
The homeless men were brought by the Pope's aide in charge of charity, Archbishop Konrad Krajewski, who has been taking Francis' concern for the poor directly to the streets of Rome.
