My church was a very traditional mennonite church up to 10 years ago. Now we sing a lot of contemporary stuff (Matt Redman, Tim Whatsisname, stuff.) 2-3 guitarists (1 acoustic, 1 electric), 1 bassist, piano, drums (really good drummer), and a small group of singers. Fun.
My old church sang hymns in Chinese. Guess what: I was illiterate in Chinese (which means lyrics on projector = useless for me), so I had to jog my mind to keep up while guessing what word came next. It really brought me down, and since I did not have a choice to go to another church, I wallowed around in a spiritual muck. The guys in charge were also WAY too conservative for me. One guy's like... "I won't talk to you guys about what men and women do together since you guys are too young..." (something to that extent). I was 17. I had already taken 4 years of sex ed in public school, as well as bio class. uh... too young? (I eventually tuned out to everythign, whcih now in hindsight, I realize that that was wrong to do.)
Problem was, though, our class had this parity: the younger kids were 12-14, and the older kids were 17-18. nothing in between.
As for hymns... Amazing Grace comes to mind, and this Chinese song called (5 AM in China) <-- talks about the underground church in China, which is surprisingly huge with a growth of over 70-90 million members since 1949.
Ultimate Avatar: I take it you go to a Christian school, no? what grade/year are you in? and where do you live? Info might help me with a sociology paper I'm writing.
