We gave you the gospel and do what is in the gospel. You do protestant heresies in contradiction to the gospel; the nonsense that there are no priests in the Gospel being one of them (1 Tim 4:14). You prove yourself. We are just fine.
This verse means that believers will storm Hell with the real weapons of our warfare
Yes, indeed. Christ storms the Gates of Hell and they do not prevail. That is the Paschal mystery that the Catholics celebrate. This is the guarantee that the Catholic Church He built prevails against all heresies and leads men to salvation always, despite Protestant lies, till He comes in glory.
