VATICAN CITY – A French nun who provided education to pioneers on the American frontier and a Mexican bishop who fought anti-clerical policies in the 1920s were among four new saints named by the pope Sunday.

Also included in the new roll call of saints named by Pope Benedict XVI were two Italians: a nun who advocated public schooling for girls in late 17th century Italy and a priest who was a trailblazer for education of the deaf.

“The Church rejoices in the four new saints,” Benedict told a crowd of several thousand people at the ceremony in St. Peter’s Square. “May their example inspire us and their prayers obtain for us guidance and courage.”

Ailing Chicago Cardinal Francis George was among those celebrating mass on the steps of St. Peter’s Basilica. He and other Americans were there to honor Mother Theodore Guerin, one of the new saints, who established St. Mary-of-the-Woods College for women in Indiana in 1841.

Despite decades of poor health, Guerin, who was born in 1798, set out with a handful of fellow French nuns for Indiana, where they founded a simple log-cabin chapel. For years, she resisted a local bishop’s opposition to her plans to establish a local community of nuns.

“Mother Theodore overcame many challenges and persevered in the work that the Lord has called her to do,” the pope said in his homily.

Phil McCord, the American whose restored vision was judged to be the miracle necessary for Guerin’s sainthood, called the ceremony “overwhelming.”

McCord, a 60-year-old engineer who manages the campus of Guerin’s order, recalled how he had faced a corneal transplant after damage from cataract surgery. He entered the chapel at the college, asked Guerin for help and his eyesight started to improve the next morning, said McCord.

Members of Guerin’s order, the Sisters of Providence of St. Mary-of-the-Woods, also attended to the ceremony. “I’ve been praying for this since I was in the third grade,” said Sister Estelle Scully. “And now I’m 80.”

Also named a saint was Mexican Bishop Rafael Guizar Valencia, who risked his life to tend to the wounded during the Mexican revolution.

In 1921, he renovated a seminary in Jalapa, Mexico, but the government later seized the building. He succeeded in having the seminary operate clandestinely for 15 years in Mexico City. He died in 1938.

Benedict hailed Guizar Valencia for working tirelessly, even facing persecution, to ensure seminarians were properly educated “according to the heart of Christ.”

At least 25,000 people paraded past the remains of Guizar Valencia all night Saturday and into Sunday in Jalapa, the capital of the Gulf coast state of Veracruz.

“We hope that (the canonization) will help people believe more easily in this Mexican saint,” said Isidro Quechuleno, a Jalapa farmer. “We really feel like he’s ours and he’s part of our religiosity.”

Guizar Valencia was a great uncle of the Rev. Marcial Maciel Degollado, the founder of the Legionaries of Christ order of priests whom the Vatican restricted from public ministry this year amid allegations Degollado sexually abused seminarians.
