You call no drinking strict rules? Wow....you need to step over to the Mennonite side
We have rules again divorce and remarriage, no smoking, no pre-maritial sex, no drinking, no swearing, etc. Aren't those every denominations "rules"? It's all coming from the same book, how couldn't you not believe those things. But it's not "rules". It's just a lifestyle, I've never heard it referred to as rules.
Also, a recommendation from me. PLEASE don't go to a truely christian school if you're not christian. It would be like a christian going to a muslem school just because they offer a particular thing, or will accept them. If you don't believe their views, why attend? But that only applies to "truely" christian schools. If they're technically a christian school, but you would never know it otherwise, then you're probably safe. But if it's purely christian and all throughout the weeks there are chapels and stuff, then you shouldn't go.
I plan on going to a very Christian(mennonite) college after I graduate HS(currently going to a private mennonite HS), and I would be greatly offended to find out there are non-christians going there. If I meet a friend or girl, I shouldn't need to ask if they're christian.
Of course, I'm not going to mention my views of Seventh Day Adventists, since it would just offend people. But it's safe to say I'm definately not one of them. Yeah, I go to church on Sunday and eat pork...I'd love for someone to prove how that's wrong.
