“However, I have learned, O Clement, how that in Alexandria Barnabas perfectly expounded to you the word respecting prophecy. Was it not so?” I answered, “Yes, and exceeding well.” Then Peter: “Therefore it is not necessary now to occupy with the instructions which you know, the time which may serve us for other instructions which you do not know.” Then said I: “You have rightly said, O Peter. But vouchsafe this to me, who purpose always to attend upon you, continuously to expound to me, a delighted hearer, the doctrine of the Prophet. For, apart from Him, as I learned from Barnabas, it is impossible to learn the truth.”
