William Henry Windsor Fanning, Catholic Encyclopedia (1913)
“ A bishop's Abdication of his see goes into effect as soon as the Pope has accepted it in a papal consistory. The bishopric then becomes vacant, but the actions of the prelate retain their validity until he receives official notice of the acceptance of his resignation. Like every other ecclesiastical dignity, the papal throne may also be resigned. The reasons which make it lawful for a bishop to abdicate his see, such as the necessity or utility of his particular church, or the salvation of his own soul, apply in a stronger manner to the one who governs the universal church. ”
