VATICAN CITY — Pope Francis appeared relaxed during his regular Sunday appearance to pilgrims at St. Peter's Square.

The pope blessed worshippers from a window overlooking the square, a day after he failed to attend a concert at the Vatican due to other commitments.

During the traditional Angelus blessing, one of the most cherished traditions of the Catholic Church, the pope spoke off the cuff, telling young people in the square to not be afraid of "going against the current."

Organizers of the Saturday concert relayed the pontiff's greetings, and said he could not attend because of "commitments that could not be postponed." The pope's spokesman did not elaborate.
