But what more iniquitous than to hold blasphemous opinions, and not to give way to those who are wiser and more learned than ourself.� Now into this unwisdom fall they who, finding themselves hindered from knowing the truth by some obscurity, have recourse not to the prophets� utterances, not to the Apostles� letters, nor to the injunctions of the Gospel but to their own selves:� and thus they stand out as masters of error because they were never disciples of truth.� For what learning has he acquired about the pages of the New and Old Testament, who has not even grasped the rudiments of the Creed?
