Pope Francis has begun his visit to the Philippines with a welcome ceremony at the presidential palace in Manila.
The pontiff was greeted by huge crowds as he arrived in the overwhelmingly Catholic country on Thursday.
On Friday he delivers a speech and then celebrates Mass in the Basilica of the Immaculate Conception in Manila.
The highlight of the papal visit will be on Sunday, when an open-air Mass is expected to attract millions of worshippers.
The pontiff says that those at the bottom on the economic ladder are the focus of his visit.
"The central nut of the message will be the poor, the poor who want to go forward, the poor who suffered from Typhoon Haiyan and are continuing to suffer the consequences," he said ahead of his arrival.
Typhoon Haiyan struck in November 2013, leaving more than 7,000 people dead or missing.
The Pope will meet survivors of the storm on Saturday in Tacloban, the worst-affected area.

Pope Francis's Philippines schedule
Millions of Filipinos are expected to come out to see Pope Francis over his five-day visit. Some 80% of the nation's 100m people are Roman Catholics.
On Friday morning, Manila's streets were crowded as the Pope began his day of events.
People have already gathered at the Basilica of the Immaculate Conception ahead of the Mass later in the day.
After that the pontiff will attend a prayer service in a stadium in Manila.
Security is very tight after failed attempts to kill two previous popes, with tens of thousands of soldiers and police deployed.
National holidays have been declared in the capital for the duration of the Pope's visit.
