Pope Benedict XVI has kicked off the Catholic Church’s Holy Week celebrations with Palm Sunday Mass in St. Peter’s Square and good news from Cuba.Cuba’s communist government on Saturday agreed to Benedict’s request to make Good Friday a holiday, a request made during his visit to the Caribbean island last week. The day, which is celebrated this Friday, marks the solemn commemoration of Christ’s death.On Sunday, Benedict travelled into St. Peter’s Square on the back of a white jeep at the start of Palm Sunday Mass, which marks Jesus’ arrival in Jerusalem and inaugurates Holy Week.Benedict and the cardinals who preceded him clutched ornately braided palm fronds, while ordinary faithful carried olive and palm branches to recreate the welcome Jesus received. St. Peter’s was nearly full under cloudy, chilly skies.The pope looked rested despite having just returned from an exhausting, six-day trip to Mexico and Cuba, where he met with former and present Cuban presidents, Fidel Castro and his brother, Raul.It was during the meeting with Raul Castro that Benedict asked that Good Friday be made a holiday, even though it isn’t celebrated as such in most of Europe and Latin America. One of the aims of Benedict’s trip was to help the local church, which has been sidelined during 30 years of official atheism that ended only in 1992.After Pope John Paul II’s historic 1998 visit to Cuba, the authorities agreed to make Christmas a holiday. Cuba said Saturday a decision on whether to make Good Friday a similarly permanent holiday would be made later.The pope, who turns 85 in two weeks, has a busy Holy Week ahead of him, with public services Thursday through Easter Sunday.Benedict directed his Palm Sunday homily to young people, urging them to welcome Christ into their lives as the people of Jerusalem welcomed him."May Palm Sunday be a day of decision for you, the decision to say yes to the Lord and to follow him all the way,” he said.
