“The gates of hell”: Just how won’t they prevail?

Matthew 16.18.

Jesus once asked his students who they thought he was. Simon Peter, his best student, correctly identified Jesus as Messiah and Son of God. Mt 16.16

(Since we Christians recognize Jesus is the Father’s only-begotten son, Jn 1.18 we tend to read that into it, rather than recognize “Son of God” as one of Messiah’s titles. In historical context it’s not what Peter meant. But I digress.)

In response Jesus pointed out how awesome this was (KJV “blessed”) because Peter hadn't just deduced it; this was a case of supernatural discernment, or special revelation. The Father had personally revealed this to Peter. Mt 16.17 Which is kinda awesome.

Then Jesus said this:

Matthew 16.18 KJV

And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.

The words Jesus used were pýlai ádu/“hades’s gates.” Latin turned this into portae inferi/“inferno’s gates.”—inferno being their word for the underworld, but in the day’s popular culture, this’d be hell. So that’s how Martin Luther, John Wycliffe, the Geneva Bible, and the King James interpreted it; and the ESV, ISV, Message, and NLT follow their lead.

But as I explained in my article on the four hells, that’s not what hades means. Hades is the grave. The afterlife. The place of the dead. That’s why other translations went with “the powers of death” (Expanded Bible, J.B. Phillips, NCV, RSV) —although that interpretation also has its problems.
