Finish the lyric Hear it getting louder, a call for revolution
Yeah, we came for what was ours, it's time for restitution
We'll protect our own, take back the stone
No, human nature cannot hold us down
Stranded at the bottom, but we're more than a whisper
No, we'll never be forgotten, our blood's thicker than silver, yeah
When worlds collide, it's do or die
So tell me, is it wrong to stand your ground?

Hear us howl, all or nothing

Fangs are out, we ain't running

Hear us howl, it's all or nothing

i believe the answer is  the similarity is that both are sacrifices which have the same purpose and sacrifice - jesus christ, but the difference is in offering of that sacrifice.

the similarity is that both are sacrifices which have the same purpose (repenting our sins) and sacrifice - jesus christ.  the difference is in the way of the offering that sacrifice. the sacrifice of jesus on the calvary is sacrifice of his actual living body and blood, but the sacrifice of the mass is the sacrifice of the jesus through bread (body) and blood (wine). in the sacrifice on calvary jesus was offered for us; while at mass he offers himself through us.
