Pope Francis was "a Pope among the people, with an open heart toward everyone," said Cardinal Giovanni Battista Re, dean of the College of Cardinals, as he presided over the funeral of the Pope, who died April 21 at the age of 88.

And the people — an estimated 200,000 of them — were present as 14 pallbearers carried Pope Francis' casket into St. Peter's Square and set it on a carpet in front of the altar for today’s funeral Mass.

His burial then took place in Rome's Basilica of St. Mary Major after being driven in a motorcade through the centre of the city where he served as bishop from the day of his election to the papacy March 13, 2013.

Security around the Vatican was tight, not only because of the number of mourners expected but especially because of the presence of kings, queens, presidents and prime ministers from more than 80 countries and official representatives from scores of other nations.

Also present were the residents of a Vatican palace Pope Francis had turned into a shelter for the homeless and the 12 Syrian refugees he brought to Rome with him from a refugee camp on the Greek island of Lesbos in 2016.

The Gospel reading at the funeral was John 21:15-19 where the Risen Jesus asks Peter, "Do you love me?" And when Peter says yes, Jesus tells him, "Feed my sheep."

"Despite his frailty and suffering toward the end, Pope Francis chose to follow this path of self-giving until the last day of his earthly life," Re said in his homily. "He followed in the footsteps of his Lord, the Good Shepherd, who loved His sheep to the point of giving His life for them."

The 91-year-old cardinal told the crowd that the image of Pope Francis that "will remain etched in our memory" was his appearance on the balcony of St. Peter's Basilica the day before he died to give his Easter blessing "urbi et orbi" (to the city and the world) and then to ride in the popemobile among the people who had come to celebrate Christ's victory over death.

"The outpouring of affection that we have witnessed in recent days following his passing from this Earth into eternity tells us how much the profound pontificate of Pope Francis touched minds and hearts," Re said. The Vatican estimated that 250,000 people — many of whom waited in line for three or four hours — filed past the late Pope's body in St. Peter's Basilica April 23-25.

Within the Church, the cardinal said, "the guiding thread" of Pope Francis' ministry was his "conviction that the Church is a home for all, a home with its doors always open." For Pope Francis, he said, the Church was a "field hospital," one "capable of bending down to every person, regardless of their beliefs or condition, and healing their wounds."

Re said that "faced with the raging wars of recent years, with their inhuman horrors and countless deaths and destruction, Pope Francis incessantly raised his voice imploring peace and calling for reason and honest negotiation to find possible solutions."

'"Build bridges, not walls' was an exhortation he repeated many times, and his service of faith as successor of the Apostle Peter always was linked to the service of humanity in all its dimensions," the cardinal said.

Re also recalled Pope Francis' constant concern for migrants and refugees from his first papal trip outside of Rome to pray for migrants who drowned in the Mediterranean Sea, his visit to Lesbos and his celebration of Mass in 2016 on the U.S.-Mexican border.

At the end of the Mass, Cardinal Baldassare Reina, papal vicar of Rome, offered special prayers for the city's deceased bishop, Pope Francis. Then Eastern Catholic patriarchs and major archbishops gathered around the casket and led funeral prayers from the Byzantine tradition in honour of the pastor of the universal Catholic Church.

Sr. Norma Pimentel, a Missionary of Jesus and director of Catholic Charities of the Rio Grande Valley in Texas, had knelt in prayer before the body of Pope Francis April 25 and was present for the funeral.

"The funeral of Pope Francis is a very important part of who we are as people of faith," she told Catholic News Service. "We walk together, we cry together, we work together ... doing what we believe is important in our lives as people of faith, and we say farewell together at the end."

The funeral, she said, is a time "to join him in this last farewell and say thank you: Thank you for being you, for being there with us, and we'll see you."

Pimentel is known especially for her work with migrants and refugees, a ministry close to the heart of Pope Francis.

"He was all about making sure that we understood the importance" of welcoming newcomers, she said. His message was: "Please open your hearts. Please care for them. That's all they're asking."
