You know Bible says no gay, right? If he wants to stay and studies in christian univ.. he must be expected lots trouble with colleagues and profs. Identity in christianity, sex=holy faith(but sex =faith study, that works)never work together. not just gender issue. He or you must clarify with .. in christ, healing pathway and freedom of choice given by god are two separate things. He or you must understand. first then make documentary. a lot easier to remove errors.
