For those responding to this thread and confused/curious about the religious issue/question of Christ - I'll just say that not all Christian sects have the same belief system regarding Jesus/who He is/what happened to Him. Not all Christians believe He 'metaphorically" died (as opposed to the belief that He really died and was really raised from the dead). I'm not speaking for the OP, but maybe her (the OP) specific Christian belief system believes His death was not 'metaphorical'. Baptists don't have the same belief system as Episcopalians, which is different from Methodists, which is still different than Catholics...yet all are within the umbrella of the 'Christian' faith. And please, let's not turn this into a holy war.
To the OP - I can understand your consternation (1) RE: the religious statements. If you're able to, I would just ignore those statements as the statements of someone with a different viewpoint than yours. My own therapist is Jewish - after we spelled out our religious boundaries and what could/could not be discussed, we've been fine. And I think a legitimate understanding of how religion may/may not impact your transition is relevant, just as any other factor in life, but if she is overtly dismissive/borderline hostile, that's a different matter. (2) RE: the sexual orientation question. To me that simply exposes inexperience on her part in dealing with the MTF community (in general), and ignorance on her part in understanding who the MTF is (in particular).
I understand the insurance issue, but if I may ask, what part of TX are you in (roundabout, not necessarily the city/town) - I've moved around in TX three times and never had issues finding a therapist.
