When my daughter (now 20) was applying to college her first choice was a catholic university. (I never forced my opinions on my kids,she actually went to religious school for grades 1-5)
She was sooo excited when we went for the campus tour... by the end of the day she was like ...”maybe not.” ???
You’ll do Great! Just take what you need and leave the rest. ?

I highly doubt you're the only doubter in any legitimate higher learning institution. I'd try the Philosophy Clubs or Natural Sciences department to start.

Most Christian colleges are accredited in theory at least; their credits will transfer to any other accredited institution, although in practice, let's just say, e.g., Harvard or MIT will not be too impressed with your grades from some random church-affiliated college.

I was dumb enough back in the day to attend an unaccredited Bible Institute -- fortunately, for only a year -- and those credits were only good at like 3 other similar institutions on the entire planet. In fact the one I went to went out of business about a decade later, a victim of its founder / leader's intransigence on the topic of accreditation, and the fact that for a little more money, you could go to the accredited Baptist university up the road (or the Christian Reformed college a few miles the other way) and transfer your credits anywhere you please. Ironically the only vestige of my alma mater that still lives on is the one practical skill they actually offered a degree in -- being a bush pilot. Those "credits" were transferable in that they took the form of a pilot's license and instrument rating and the like.

Some of these institutions teach science in the technical sense that satisfies the accreditation bodies but are always qualifying and undermining it in practice, as their dogma requires that you be a young earth creationist or at least to subscribe to theistic evolution. They are generally weak on STEM disciplines. I'd check the reputation of the institution outside of church circles; you'll generally find them lackluster at best compared to even the state universities. If you're trying to save $$ you'll get what you pay for ... and may be surprised at what you can put together with grants and scholarships at a state U in your home state.

Good luck. Beware of those who would have you cry and sob telling Jebus that you are sorry. Some believers get their jollies this way. They talk nonsense to you.

My daughter spent her first year at a Jesuit college - La Salle. She had a mandatory religion class where she earned an A. What got me, at a well received school, the woman teaching the class thought everyone was christian, until my daughter raised her hand, and, that the woman, teaching college religion, needed my daughter to explain what an Unitarian Universalist was.

Please say it is not LU.

Are there any religious studies in your course requirements to graduate? That'll be the tough part to sit through but treat it as a sociological experiment to observe the sheep in their natural habitat lol and subvert the system quietly when possible. Good luck!
