[continued ^ ] So here is the part of Gaebelein's commentary he refers to (in the above post and quote of him) regarding 1Pet3 under discussion:
[quoting]
"The chief question is: Did our Lord go to Hades in a disembodied state? In fact, all depends on the question of what is the true meaning of the sentence, “quickened by the Spirit.” Now, according to the interpretations of the men who teach that the Lord visited Hades, the spirits in prison, during the interval between His death and the morning of the third day, He descended into these regions while His dead body was still in the grave. Therefore, these teachers claim that His human spirit was quickened, which necessitates that the spirit which the dying Christ commended into the Father’s hands had also died. This is not only incorrect doctrine, but it is an unsound and evil doctrine. Was the holy humanity of our Lord, body, soul and spirit dead? A thousands times No! Only His body died; that is the only part of Him which could die. The text makes this clear: “He was put to death in flesh,” that is, His body. There could be no quickening of His spirit, for His spirit was alive. Furthermore, the word quickening, as we learn from
Ephesians 1:20 and
Ephesians 2:5-6, by comparing the two passages, applies to His physical resurrection, it is the quickening of His body. To teach that the Lord Jesus was made alive before His resurrection is unscriptural. The “quickened by the Spirit” means the raising up of His body. His human spirit needed no quickening; it was His body and only His body. And the Spirit who did the quickening is not His own spirit, that is, His human spirit, but the Holy Spirit.
Romans 8:11 speaks of the Spirit as raising Jesus from among the dead.
"We have shown that it was an impossibility that Christ was in any way quickened while His body was not yet raised, hence a visit to Hades is positively excluded between His death and resurrection. There is only another alternative. If it is true that He descended into these regions, then it must have been after His resurrection. But that is equally untenable. The so-called “Apostle’s Creed” puts the descent between His death and resurrection and all the other theorists follow this view. We have shown what the passage does not mean. It cannot mean a visit of the disembodied Christ to Hades, for it speaks of the quickening by the Spirit, and that means His physical resurrection."
