Pope Leo XIV arrived in Spain on Saturday for a weeklong visit to one of Europe's traditional centers of Christianity.

His visit is expected to focus on immigration and social justice.

According to the planned schedule, the Vatican said the Pope will:

• Start with a welcome at the royal palace in Madrid from King Felipe VI and Queen Letizia
• Attend a prayer vigil near Real Madrid's Santiago Bernabeu Stadium where 400,000 people are expected
• Meet young people in the square outside the stadium
• Attend Mass in the city center on Sunday, where a million people are expected.
• Make a speech to the Spanish Parliament
• Bless the new tower of the Sagrada Familia Basilica in Barcelona, now the world's tallest church
• Meet with some victims of sexual abuse by Catholic clergy
• End his visit with a two-day stop in the Canary Islands, where Pope Leo will meet with migrants and the humanitarian organizations providing care for them

Pope to address parliament

This is US-born Pope Leo's first trip to an EU country outside of Italy and the first papal trip to Spain in more than 15 years.

Vatican spokesman Matteo Bruni said the Pope's central message will be for young people to help them "envisage the future, even in an age of strongmen, where the church seeks to foster holy men."

The Papal speech on Monday to both chambers of the Spanish Parliament will underline the visit. No pope has ever addressed Spanish Parliament before.

It comes at a time when Prime Minister Pedro Sanchez faces mounting political pressure over corruption scandals.
