DORCHESTER (CBS) — Hundreds of parishioners packed into Mother Teresa of Calcutta Parish to hear Cardinal Sean O’Malley speak about Mother Teresa, who was made a saint by Pope Francis on Sunday.

At a mass Sunday morning, he called her a woman with a joyful spirit, someone who made a huge impact on the life of the church and the world through her example of mercy, love, charity, and self-giving.

O’Malley said Mother Teresa loved with no expectation of being loved in return.

“She would go to places where there was war, and people were hating each other and fighting with each other,” said O’Malley. “She would teach them to love each other, and to love first–not to wait for the other person to love you. They may never love you, but you have to love them first, you have to forgive first. And she did that so well.”

Several sisters from the order Teresa founded, the Missionaries of Charity, had front-row seats for the mass.

O’Malley said she was a model for today’s Christians.

“All of us think of saints of people who lived in far-away places and long ago,” he said. “And here is a woman from our own age who visited Boston and New Bedford, traveled all over the world to take care of the poorest of the poor.”

“Her life was an inspiration to so many,” he said.
