Do American Christian Universities and Colleges offer as high quality education as other countries? I'm asking specifically about Science courses.

The Kurt Wise case does not reflect on Harvard though it's a Christian University, I understand that. He rejected it because he was convinced geology was biblical, not actual.

It's just that since high school (a few years after 9th grade, translated), the factor in common in discourse has been that proponents making claims incompatible with what I've learned all have Christian Universities as their Alma Mater.

I'm from Sweden and can study in the United States, anywhere in EU, and Switzerland but not Norway.

I would like to finish my studies in the United States. Am I being overly cautious? Are there differences as to what I will be taught, depending on which University?

My application would be for geology with archaeology as minor.
Christian universities in the United States are tremendously diverse.  The fact that a particular university is "Christian" tells you only that it is not a government owned university.  Almost no other conclusions can be drawn from a Christian identity.  

Each university makes its own curriculum.  A science department at one university may exclusively teach science based on religious beliefs.  A science department at another "christian" university might not employ anyone who knows anything about christianity.
