Since, again, some who are reckoned among the orthodox go beyond the pre-arranged plan for the exaltation of the just, and are ignorant of the methods by which they are disciplined beforehand for incorruption, they thus entertain heretical opinions. For the heretics, despising the handiwork of God, and not admitting the salvation of their flesh, while they also treat the promise of God contemptuously, and pass beyond God altogether in the sentiments they form, affirm that immediately upon their death they shall pass above the heavens and the Demiurge, and go to the Mother (Achamoth) or to that Fr. whom they have feigned. Those persons, therefore, who disallow a resurrection affecting the whole man (universam reprobant resurrectionem), and as far as in them lies remove it from the midst [of the Christian scheme], how can they be wondered at, if again they know nothing as to the plan of the resurrection? For they do not choose to understand, that if these things are as they say, the Lord Himself, in whom they profess to believe, did not rise again upon the third day; but immediately upon His expiring on the cross, undoubtedly departed on high, leaving His body to the earth. But the case was that for three days He dwelt in the place where the dead were, as the prophet says concerning Him: “And the Lord remembered His dead saints who slept formerly in the land of sepulture; and He descended to them, to rescue and save them.” And the Lord Himself says, “As Jonah remained three days and three nights in the belly of the fish, so shall the Son of man be in the heart of the earth.” [Matt. 11:40]
Then also the apostle says, “But when He ascended, what is it but that He also descended into the lower parts of the earth?” [Eph. 4:9] This, too, David says when prophesying of Him, “You have delivered my soul from the depths of Sheol” [Ps 86:13] and on His rising again the third day, He said to Mary, who was the first to see and to worship Him, “Touch Me not, for I have not yet ascended to the Fr.; but go to the disciples, and say unto them, I ascend unto My Fr., and unto your Fr..” [John 20:17]
If, then, the Lord observed the law of the dead, that He might become the first-begotten from the dead, and tarried until the third day “in the lower parts of the earth;” [Eph. 4:9] then afterwards rising in the flesh, so that He even showed the print of the nails to His disciples, [John 20:20,27] He thus ascended to the Fr.;–[if all these things occurred, I say], how must these men not be put to confusion, who allege that “the lower parts” refer to this world of ours, but that their tuner man, leaving the body here, ascends into the super-celestial place? For as the Lord “went away in the midst of the shadow of death,” [Ps. 23:4] where the souls of the dead were, yet afterwards arose in the body, and after the resurrection was taken up [into heaven], it is manifest that the souls of His disciples also, upon whose account the Lord underwent these things, shall go away into the invisible place allotted to them by God, and there remain until the resurrection, awaiting that event; then receiving their bodies, and rising in their entirety, that is bodily, just as the Lord arose, they shall come thus into the presence of God. “For no disciple is above the Master, but every one that is perfect shall be as his Master.” [Luke 6:40] As our Master, therefore, did not at once depart, taking flight [to heaven], but awaited the time of His resurrection prescribed by the Fr., which had been also shown forth through Jonah, and rising again after three days was taken up [to heaven]; so ought we also to await the time of our resurrection prescribed by God and foretold by the prophets, and so, rising, be taken up, as many as the Lord shall account worthy of this [privilege].
