WASHINGTON â Next week,Pope Benedict XVI will canonize seven saints including two Americans: Blessed Kateri Tekakwitha, the first Native American saint, and Blessed Mother Marianne Cope, who spent the last 30 years of her life ministering to the sick on the Hawaiian island of Molokai.
Pope Benedict XVI's decision to step down as leader of the Catholic Church made him the first pope to relinquish the office since Pope Gregory XII in 1415 (who did so in order to end the Western Schism), and the first to do so on his own initiative since Pope Celestine V in 1294.
