In this paper we present the main theories concerning the interpretation of 1 Peter 3:19. The entire vocabulary of this problematic text is analysed in details, attempting to draft which of the previous theories best fit the current context. 1 Peter 4:6 is also examined in passing, aiming to determine the relation between 1 Peter 3:19 and 4:6. Besides we give a kerygmatic explanation of the text in order to formulate its message for the readers of our days.
