Here's something I posted some time back, on that 1 Peter 3 passage:
[quoting Gaebelein on 1 Peter 3]
"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.
"What, then, does the passage mean? It is very simple after all. He preached by the Spirit, or in the Spirit, that is, the same Spirit who raised Him from among the dead, the Holy Spirit of life and power,
to the spirits who are now in prison. But when the preaching occurred they were not in prison. And who were they? All the wicked dead for 4,000 years?
The text makes it clear that they are a special class of people. They were living in the days of Noah. It is incomprehensible how some of these teachers, misinterpreting this passage, can teach that it includes all the lost, or angels which fell, or the righteous dead. The Spirit of God preached to them, that is,
the Spirit who quickened the body of Christ,
the same Spirit preached to the generation of unbelievers
in the days of Noah. The time of the preaching, then, did not occur between the death and resurrection of Christ, but it took place in Noah’s day. Christ was not personally, or corporeally present, just as He is not present in person in this age when the gospel is preached; His Spirit is here.
"
So was He present by His Spirit in the days of Noah. It is written: “My Spirit shall not always strive with man, for that he also is flesh; yet his days shall be one hundred and twenty years” (Genesis 6:3).
His Spirit was then on the earth. In long-suffering God was waiting for one hundred and twenty years while the ark was preparing.
His Spirit preached then. But He needed an instrument. The instrument was Noah; in him was the Spirit of Christ and as the preacher of righteousness (2Peter 2:5) he delivered the warning message of an impending judgment to those about him, who did not heed the message, passed on in disobedience, were swept away by the deluge
and are now the spirits in prison.
As the Spirit of Christ was in the prophets (1Peter 1:11) testifying beforehand of the suffering of Christ and the glory that should follow, so the Spirit of Christ preached through Noah. This is the meaning of this passage, and any other is faulty and unscriptural."
