Several schemata consider the Church too much as an institution under siege which the Council must defend; they do not see in it enough the radiant depositary of the salvation to be shared. In them the Church has the aspect of an institution more juridical than missionary. They don’t show the courage to turn frankly to the present world, toward its needs, toward its new and legitimate demands. They seem to believe, instead, that it will be enough to repeat, with more insistence but without deepening the doctrine, formulas which already the world no longer can understand. They seem to believe that the losses of faith, the deterioration of morality, the failures of the apostolate have no other causes than the inattention of men or the malice of the times; they do not ask if the obsolete character of certain forms of the Church’s thought and action also play some role in it.
