Pope Benedict XVI has named Bishop Samuel J. Aquila of Fargo, N.D., as the new archbishop of Denver and also named Bishop Richard J. Malone of Portland, Maine, to head the Diocese of Buffalo, N.Y.

The pope also accepted the resignation of Buffalo Bishop Edward U. Kmiec, who is 75, the age at which canon law requires bishops to submit their resignation to the pope.

Archbishop Aquila, 61, succeeds Archbishop Charles J. Chaput, who was named to head the Philadelphia Archdiocese last July. The new archbishop has headed the Fargo Diocese since 2002. Bishop Malone, 66, has been Portland’s bishop since 2004.
