When the king's son had heard these words, there flashed a light upon his soul. Rising from his seat in the fulness of his joy, he embraced Barlaam, saying: "Most honoured sir, methinks this might be that priceless stone which thou dost rightly keep secret, not displaying it to all that would see it, but only to these whose spiritual sense is strong. For lo, as these words dropped upon mine ear, sweetest light entered into my heart, and the heavy veil of sorrow, that hath now this long time enveloped my heart, was in an instant removed. Tell me if my guess be true: or if thou knowest aught better than that which thou hast spoken, delay not to declare it to me." Again, therefore, Barlaam answered, "Yea, my lord and prince, this is the mighty mystery which hath been hid from ages and generations, but in these last days hath been made known unto mankind; the manifestation whereof, by the grace of the Holy Ghost, was foretold by many prophets and righteous men, instructed at sundry times and in divers manners. In trumpet tones they proclaimed it, and all looked forward to the salvation that should be: this they desired to see, but saw it not. But this latest generation was counted worthy to receive salvation. Wherefore he that believeth and is baptized shall be saved; but he that believeth not shall be damned." Said Ioasaph, "All that thou hast told me I believe without question, and him whom thou declarest I glorify as God. Only make all plain to me, and teach me clearly what I must do. But especially go on to tell me what is that Baptism which thou sayest that the Faithful receive."
