"The "pragmatist" and the "agnostic" may be quite sincere and well-meaning; but they only deceive themselves--and others--if they continue to use the word "truth" to describe what they are seeking. Their existence, in fact, is testimony to the fact that the search for truth which has so long animated European man has come to an end. Four centuries and more of modern thought have been, from one point of view, an experiment in the possibilities of knowledge open to man, assuming that there is no Revealed Truth. The conclusion--which Hume already saw and from which he fled..."
St. Justin Popovich (+1979): “All the European humanisms, from the most primitive to the most sophisticated, from the fetishistic to the papal, are based on a belief in man as he finds himself in the midst of his given spiritual and physical empirical situation and his historical context. In this view the entire essence of every humanism is man (homo), and encapsulated in the ontology of every humanism is nothing other than humanism (homo hominis)....Through this dogma all European humanisms have built their ideals and their idol: man has been declared the supreme godhead, the ultimate godhead. The European humanistic pantheon has established its Zeus.”

"How do you respond to those who say that Christ the Miracle-worker cannot fit into our logic? Simply reply: Fit yourself into His logic. In His logic, all eternity fits and all the nobleness of time--and so, if you wish, a place will be found even for you. If a barrel cannot fit into a thimble, you can fit a thimble into a barrel." -St Nikolai Velimirović of Serbia (+1956)
