Peter having preached the word publicly at Rome, and by the Spirit proclaimed the Gospel, those who were present, who were numerous, entreated Mark, inasmuch as he had attended him from an early period, and remembered what had been said, to write down what had been spoken. On his composing the Gospel, he handed it to those who had made the request to him; which coming to Peter’s knowledge, he neither hindered nor encouraged. But John, the last of all, seeing that what was corporeal was set forth in the Gospels, on the entreaty of his intimate friends, and inspired by the Spirit, composed a spiritual Gospel.
