One indisputable dogma presupposes an infallible Church.
--Auguste Sabatier in Sertillanges, Catéchisme des Incroyants II, Flamarrion, 1930, p. 59.

Someone has to decide.
Why not the one chosen by Christ to be his Vicar on earth, Saint Peter and his successors, the Popes of the Catholic Church! Cf. Matt 16:18
