Ante-Nicene Fathers, Vol IX:
Epistle to Gregory and Origen's Commentary on the Gospel of John.: Chapter IX

9.  The Somatic and the Spiritual Gospel.

We must not, however, forget that the sojourning of Christ with men took place before His bodily sojourn, in an intellectual fashion, to those who were more perfect and not children, and were not under pedagogues and governors.  In their minds they saw the fulness of the time to be at hand—the patriarchs, and Moses the servant, and the prophets who beheld the glory of Christ.  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.  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.  In accordance with this we may conclude that, as it is with Him who is a Jew outwardly and circumcised in the flesh, so it is with the Christian and with baptism.  Paul and Peter were, at an earlier period, Jews outwardly and circumcised, but later they received from Christ that they should be so p. 302 in secret, too; so that outwardly they were Jews for the sake of the salvation of many, and by an economy they not only confessed in words that they were Jews, but showed it by their actions.  And the same is to be said about their Christianity.  As Paul could not benefit those who were Jews according to the flesh, without, when reason shows it to be necessary, circumcising Timothy, and when it appears the natural course getting himself shaved and making a vow, and, in a word, being to the Jews a Jew that he might gain the Jews—so also it is not possible for one who is responsible for the good of many to operate as he should by means of that Christianity only which is in secret.  That will never enable him to improve those who are following the external Christianity, or to lead them on to better and higher things.  We must, therefore, be Christians both somatically and spiritually, and where there is a call for the somatic (bodily) 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.
