Andreas of Caesarea — on 1Pet 3:18 (CATENA)

“Again Peter expounds Christ's death and resurrection. Notice how he proclaims the mystery to us. For by saying that he died in the flesh and that he was made alive again in the Spirit, what he is really saying is that he died for the sake of our flesh, which is under the power of corruption, but that he rose again as God, for the word spirit means "God" in this instance.”
