Instead, the Vatican sent Tolton to a different mission field, the United States, where many believe he was the first African-American priest ordained in the Catholic Church.
The next steps to sainthood would be beatification, followed by canonization. Officials in Rome are reviewing at least one potential miracle attributed to Tolton's intercession, according to the Diocese of Springfield in Illinois, which has been working on the priest's cause of canonization with the Archdiocese of Chicago since 2003.
"Father Tolton leaves us a shining example of what Christian action is all about, what patient suffering is all about in face of life's incongruities," said Bishop Joseph Perry of the Archdiocese of Chicago and a chief advocate of Tolton's cause for canonization. "He was a bright light in a difficult period of this nation's history."
They later moved to Quincy, Illinois, where Tolton attended an all-white Catholic school.
Because no American seminary would accept a black man, the diocese said, Tolton studied in a Roman seminary, returning to the United States at age 31.
"After years of enduring racism from some members of the community, including a priest, he later accepted an assignment in Chicago," the Diocese of Springfield said, "continuing his service to the poor and marginalized. Father Tolton died in 1897 at the age of 43 from heat stroke."
