Origen

“ And this, too, we must bear in mind, that as the law contains a shadow of good things to come, which are indicated by that law which is announced according to truth, so the Gospel also teaches a shadow of the mysteries of Christ, the Gospel which is thought to be capable of being understood by any one. What John calls the eternal Gospel, and what may properly be called the spiritual Gospel, presents clearly to those who have the will to understand, all matters concerning the very Son of God, both the mysteries presented by His discourses and those matters of which His acts were the enigmas. ”

“ Gospel, in which a man says to those who are carnal that he knows nothing but Jesus Christ and Him crucified, so we must do. But should we find those who are perfected in the spirit, and bear fruit in it, and are enamoured of the heavenly wisdom, these must be made to partake of that Word which, after it was made flesh, rose again to what it was in the beginning, with God. ”

“ And as before His manifest and bodily coming He came to those who were perfect, so also, after His coming has been announced to all, to those who are still children, since they are under pedagogues and governors and have not yet arrived at the fulness of the time, forerunners of Christ have come to sojourn, discourses (logoi) suited for minds still in their childhood, and rightly, therefore, termed pedagogues. But the Son Himself, the glorified God, the Word, has not yet come; He waits for the preparation which must take place on the part of men of God who are to admit His deity. ”
