At that time, he compared abortion and stem-cell research to slavery and racism. Archbishop of Detroit Pope Benedict XVI appointed Vigneron as archbishop of the Archdiocese of Detroit on January 5, 2009, replacing Cardinal Maida. Installed on January 28, 2009, Vigneron was the first Detroit native named archbishop of Detroit.
