Hi, current student of Gutenberg here.
I didn't have to agree to any theological premises to come to the school. Full-time faculty, not incoming students, sign a Biblical Foundation Statement.
Our tutors take their own religious beliefs seriously and also give you plenty of space for your own beliefs.  The goal is to understand and be fair to the writers and to each other.  We don't all come to the same conclusions all the time.
Students are not scared to disagree with our tutors, and no, they don't grade us down for disagreeing.  We're all just here to read great books and wrestle with their meaning.
