I’m writing a book but I need some inspiration. It’s called The Mirror and it’s about vampires. Any help would be appreciated.

Maybe something like a world full of vampires that can only access the human world through a mirror and can copy the face of the last person who used the mirror as a disguise to come out and suck blood every night

Explanation:

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.
