Catena Aurea · Johannesevangelium 18
Then Pilate entered into the judgment hall again, and called Jesus, and said unto him, Art thou the King of the Jews? Jesus answered him, Sayest thou this thing of thyself, or did others tell it thee of me? Pilate answered, Am I a Jew? Thine own nation and the chief priests have delivered thee unto me: what hast thou done? Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence. Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice. Pilate saith unto him, What is truth? Jesus answered him, Sayest thou this thing of thyself, or did others tell it thee of Me?
(Tr. cxv) But when Christ bears witness to the truth, He bears witness to Himself; as He said above, I am the truth. (c. 14:6) But inasmuch as all men have not faith, He adds, Every one that is of the truth heareth My voice: heareth, that is, with the inward ear; obeys My voice, believes Mc. Every one that is of the truth, hath reference to the grace by which He calleth according to His purpose. For as regards the nature in which we are created, since the truth created all, all are of the truth. But it is not all to whom it is given by the truth to obey the truth. For had He even said, Every one that heareth My voice is of the truth, it still would be thought that such were of the truth, because they obeyed the truth. But He does not say this, but, Every one that is of the truth heareth My voice. A man then is not of the truth, because he hears His voice, but hears His voice because he is of the truth. This grace is conferred upon him by the truth.
