Matthew 16:18
Douay-Rheims
And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.
Jerome
I suppose the gates of hell to mean vice and sin, or at least the doctrines of heretics by which men are ensnared and drawn into hell.
