The first publicly recognized Black priest in the United States, Augustus Tolton, may not be a household name. Yet I believe his story - from being born enslaved to becoming a college valedictorian - deserves to be a staple of Black History Month. "Good Father Gus" is now a candidate for sainthood. My forthcoming book, " The Wounded Church," examines ways that the Catholic Church has excluded people during different chapters of its history, from women to African American people.
