Pope overcomes health concerns, presides over blustery Easter Sunday Mass in St. Peter's Square

Pope Francis ditched his Palm Sunday homily last week and decided at the last minute to stay home from the Good Friday procession at the Colosseum

Pope Francis overcame concerns about his health to preside over Easter Sunday Mass, leading tens of thousands of people in a flower-decked St. Peter's Square in one of the most important liturgies of the year.

Just hours after celebrating the 2½-hour nighttime Easter Vigil, the 87-year-old Francis appeared in good form at the start of the liturgy in the blustery piazza. Francis, who had part of one lung removed as a young man, has been battling respiratory problems all winter that the Vatican and he have said were bronchitis, the flu or a cold.

Easter Mass is one of the most important dates on the liturgical calendar, celebrating what the faithful believe was Jesus resurrection after his crucifixion. The Mass precedes the pope's Urbi et Orbi (to the city and the world) blessing, a lengthy speech that traditionally rounds up all the threats facing humanity.

For the past few weeks, Francis has generally avoided delivering long speeches to avoid the strain on his breathing. He ditched his Palm Sunday homily last week and decided at the last minute to stay home from the Good Friday procession at the Colosseum.

The Vatican said in a brief explanation that the decision was made to conserve his health. The decision appeared to have paid off, as Francis was able to recite the prayers of the lengthy Saturday night Easter Vigil service, including administering the sacraments of baptism and First Communion to eight new Catholics, and preside over Easter Sunday Mass.

After a busy Holy Week, Francis should have some time to recover as there are no major foreign trips scheduled for several months.
