Be careful: what is a Christian college? Only a very few Christian colleges offer Ph.D.s. This means that the majority of Christian College faculties are trained in secular universities. That means there is no guarantee that Christian faculty will have a world view different from secular university faculty.
As a rule of thumb, in my opinion, evangelical students should try to attend Christian colleges. The fact is, if you are planning to attend graduate school, undergraduate degrees (if they are accredited) are more or less perceived equally by most graduate schools. If you have any doubt, phone the school and ask where their students attend graduate school.
Finally, in many ways it is a moot point. The majority of evangelical parents prefer to send their students to local, state or community colleges. Why? Cost. You can save on tuition and housing costs. In fact, it is not a bad idea to take most of your basic courses at a community or junior college. Keep this in mind, though. Transfer students with two years of college (c. sixty credits) virtually never receive financial aid. So, if you have a chance to receive scholarship aid, it might be more financial feasible for you to attend a four year undergraduate school immediately after high school graduation.
Speaking of graduation, why don’t some of you home school students consider a senior mission year? My son, Peter, finished his academic work junior year, obtained a good SAT Score, and spent his senior year suffering for Jesus at Maui (as in Maui, Hawaii) Bible College. It was a very positive experience for him. When he finished Bible College, he applied to college (his SAT scores were current) and he began his undergraduate education at Liberty University, Lynchburg, Virginia.
Some students wisely learn a trade before they begin undergraduate school. For instance, I have heard of a young man (home schooled) who learned how to wire houses. While an undergraduate and then a graduate student at Cornel University, he paid his way through college by wiring houses. When he graduated with a Ph. D. in electrical engineering he had no debt and obviously he was very employable.
