As for infallibility, this was a direct grace of God, given only to the few.
The minority, among whom were prominent Ca" "pals Rauscher and Schwarzenberg, Hefele, bishop of Rotterdam (the historian of the councils) Cardinal Mathieu, Mgr Dupanloup, Mgr Maret, &c., &c., did not pretend to deny the papal infallibility; they pleaded the inopportuneness of the definition and brought forward difficulties mainly of an historical order, in particular the famous condemn ion of Pope Honorius by the 6th ecumenical council of Const: ntinople in 680.
He gave a vigorous support to the promulgation of the dogma of Papal Infallibility in 1870.
The substance of the claim to infallibility made by the Roman Catholic Church is that the Church and the pope cannot err when solemnly enunciating, as binding on all the faithful, a decision on a question of faith or morals.
In ecclesiastical policy his views were moderate; thus he opposed the definition of the dogma of papal infallibility both before and during the Vatican council, but was among the first to accept the dogma when decreed.
