Hi StrC,
Most Christian schools encourage broad doctrine, but will ask you to sign a statement that you agree with the basic tenets of Christian faith, and will abide within respectable conduct limits.
Some schools have no smoking/no drinking policies. Most will have separate male and female dormitories, with curfews or sign-ins. There are even secular schools now that ask for no drinking on campus, because of the liability issues.
I would guess that most schools will just ask you to write out a statement of your own faith, and then suggest you might find a better fit elsewhere if you are out in left field. They might not even do that. Smaller independent schools tend toward tighter doctrine restrictions, especially if they are denominational or training people to be missionaries and pastors. But most of the accredited schools are not. Accredited courses are not supposed to teach dogma.
Decades ago schools were more stringent in personal expectations; now there are laws that protect people from discrimination.
I can think of one Christian school that willingly accepts agnostic students, and teachers if they are adjunct. But they offer a Christian atmosphere by ensuring that full-time teachers are willing to promote the mission of the institution.
Your stance on Yeshua is more than most would want to deal with, but once you are in, there really won't be many times it will come up. Unless you make it an issue.
That is, signing up for theology courses will put you in a position of writing many papers and presenting your findings convincingly. If you are a computer science major, it might come up once or twice in your general studies courses.
I attended a Christian college, and found it a great atmosphere for learning. I would recommend it even if you were a Muslim or atheist, because there is a greater premise of self-discipline. Friends don't brag about staying up all night gaming, come to class late with a hangover, steal each others' Ritalin, or talk about cheating on a project. Your peers will generally be responsible people who are there to learn and make friends.
I am certainly not saying that secular campuses are evil, but I see time spent more effectively on Christian campuses.
Feel free to PM me with questions. You can also check the admissions pages on their web sites. I know a couple people who went to Gordon and loved it...almost commutable.
