St. Francis de Sales: "Now when he [a Pope] is explicitly a heretic, he falls ipso facto from his dignity and out of the Church ."

"Or, quand il est heretique expres, ipso facto, il tumbe de son grade hors de l’Eglise..."

"Now when he [a Pope] is explicitly a heretic, he falls ipso facto from his dignity and out of the Church, and the Church must either deprive him, or, as some say, declare him deprived, of his Apostolic See." St. Francis de Sales, "The Catholic Controversy"
