Recouping the cost of my seminary education

Last night I joined some friends for Team Trivia at a local pizza joint. This particular team of folks has a pretty good record at Team Trivia. Seldom do we finish out of the top three, and we often win. This week we were struggling a bit and were right in the thick of things leading into the final round and final question. Twice during the evening, information garnered from being a seminary trained member of the clergy came in handy. The first question came early in the evening, while the second was the final and decisive question that allowed us to bury everyone else by 20 points, thus allowing me to recoup $25 of the cost of my seminary education in the form of house cash.

So, Renderings fans, here are the questions. The answers will follow tomorrow:

1. One word may be used to describe the following three things:
1. A holy sacramental bread
2. What a parasite feeds off of
   
3. Alex Trebek

What is the word?

2. The last book of the New Testament is called Revelation (the guy running trivia said "Revelations" but I let that slide). What else is the book of Revelation called?

Please hold off on answering in the comments section so others may have the fun of trying to figure it out.
