Saints In Hell Lyrics

I'm not sure what this song is based on besides Christian hell and saints. What is the bell they refer to? Is it something to do with "For Whom the Bell Tolls"?. I've read of the idea called the "Harrowing of Hell"(or "Descent of Christ into Hell") where Jesus is supposed to have gone into hell for the 3 days in between his death and resurrection, which is part of some Christian writings not included in the New Testament. But I think the song is probably based around it's ironic title. The irony of saints being in hell.
