Pope Benedict XVI has called for "solidarity" with refugees from conflict, in particular Africans, in his Easter message to the world.
"May help come from all sides to those fleeing conflict and to refugees from various African countries who have been obliged to leave all that is dear to them," the Pope said in his Easter message in St Peter Square.
"May people of goodwill open their hearts to welcome them, so that the pressing needs of so many brothers and sisters will be met with a concerted response in a spirit of solidarity," he added.
Earlier, Pope Benedict XVI marked the holiest night of the year for Christians by stressing that humanity is not a random product of evolution.
Benedict emphasised the Biblical account of creation in his Easter Vigil homily, saying it was wrong to think at some point "in some tiny corner of the cosmos there evolved randomly some species of living being capable of reasoning and of trying to find rationality within creation, or to bring rationality into it.
"If man were merely a random product of evolution in some place on the margins of the universe, then his life would make no sense or might even be a chance of nature," he said.
"But no, reason is there at the beginning: creative, divine reason."
Church teaching holds that Catholicism and evolutionary theory are not necessarily at odds.
A Christian can, for example, accept the theory of evolution to help explain developments, but is taught to believe that God, not random chance, is the origin of the world.
The Vatican, however, warns against creationism, or the overly literal interpretation of the Biblical account of creation.
Benedict's voice was hoarse and he coughed several times during the three-hour service, which ended after midnight.
It was the second late night in a row for the 84-year-old pontiff following his participation in the Good Friday Way of the Cross procession at Rome's Colosseum, which commemorates Jesus' death.
The Easter Vigil is the most important liturgy on the church's calendar, when the faithful mark the passage from Christ's death to his resurrection on Easter Sunday.
It is rich with symbols: fire and light signifying Jesus' resurrection, and the water used to baptise people into the faith.
Last night, Benedict baptised six adults from Switzerland, Albania, Russia, Peru, Singapore and China, pouring water over their heads as he prayed.
Benedict began the service by lighting a candle and walking down a darkened central aisle of St Peter's Basilica in silence, while hundreds of faithful in the pews shared the flame from candle to candle until the entire basilica twinkled.
