After the service, Singapore’s archbishop, Cardinal William Goh, paid tribute to the late pontiff.
“Pope Francis really is a man for all, a man who has a heart for the vulnerable, the sick, marginalised, and those who are suffering,” he said.
During the Homily, he added that the pope was a man who cared for everyone, regardless of whether they were Catholics.
The Catholic Church will observe a nine-day period of mourning, said Mr Andre Ahchak, a spokesperson from the Roman Catholic Archdiocese of Singapore.
There will be a dedicated online space on the CatholicSG website for people to leave messages of condolences, he added. Parishes across the archdiocese will organise their own memorial events and prayer vigils.
Born Jorge Mario Bergoglio, Pope Francis was the first Latin American leader of the Roman Catholic Church.
Earlier this year, the pontiff spent five weeks in the hospital for double pneumonia. He left the facility in March and last appeared in St Peter’s Square on Easter Sunday.
Cardinals are due to meet on Tuesday to plan Pope Francis’ funeral. The Vatican has said it expects the ceremony to take place sometime between Friday and Sunday.
Pope Francis will become the first pope in more than 100 years to be laid to rest outside the Vatican. He rejected the tradition of having three coffins and chose to be buried in just a single coffin made of wood and zinc.
