Born in Guarantingueta near São Paulo, Antônio attended the Jesuit seminary in Belem, but later decided to become a Franciscan friar and was ordained a priest in 1762.
In São Paulo, he served as preacher, confessor, and porter. Within a few years, he was appointed confessor to the Recollects of Saint Teresa, a group of nuns in that city. He and Sister Helena Maria of the Holy Spirit founded a new community of sisters under the patronage of Our Lady of the Conception of Divine Providence. Sister Helena Maria’s premature death the next year left Father Antônio responsible for the new congregation, especially for building a convent and church adequate for their growing numbers.
He was beatified in Rome on October 25, 1998, and canonized in 2007.Saint of the Day
