It is not possible that the Gospels can be either more or fewer in number than they are. For there are four zones of the world in which we live, and four principal winds, while the church is scattered throughout the world. And the pillar and ground[1] of the church is the gospel and the Spirit of life. So it is fitting that she should have four pillars, breathing out immortality on every side and making people alive once more. From which fact, it is evident that the Word, the Craftsman of all things, who sits upon the cherubim and contains all things, who was manifested to humankind, has given us the gospel under four aspects but bound together by one Spirit. As also David says, when praying to the manifestation of the Word, You, who sit between the cherubim, shine forth.[2] For the cherubim, too, were four-faced, and their faces were images of the dispensation of the Son of God. For, [as the Scripture] says, The first living creature was like a lion, symbolizing his effectual working, his leadership and royal power. The second [living creature] was like a calf, signifying [his] sacrificial and priestly order. But the third had, as it were, the face as of a man, an evident description of the Word’s advent as a human being. The fourth was like a flying eagle, pointing out the gift of the Spirit hovering with his wings over the church. And therefore the Gospels are in accord with these things, among which Christ Jesus is seated. For the Word, according to John, relates his original, effectual and glorious generation from the Father, thus declaring, In the beginning was the Word, and the Word was with God, and the Word was God.[3] Also, all things were made by him, and without him was nothing made. For this reason, too, is that Gospel full of all confidence, for such is his person. But that according to Luke, the taking up [his] priestly character, commenced with Zechariah the priest offering sacrifice to God. For now was made ready the fatted calf, about to be sacrificed by fire for the finding again of the younger son.[4] Matthew, again, relates his generation of Jesus Christ, the son of David, the son of Abraham.[5] And also, the birth of Jesus Christ happened this way.[6] This, then, is the Gospel of his humanity. For which reason it is, too, that [the character of] a humble and meek man is sustained through the whole Gospel. Mark, on the other hand, commences with [a reference to] the prophetic spirit coming down from on high to men. He says, The beginning of the Gospel of Jesus Christ, as it is written in Isaiah the prophet,[7] pointing to the winged aspect of the Gospel. On this account he made a compendious and cursory narrative, for such is the prophetic character.
