I think that the military should discharge her for gross fraudulence in claiming to be a Pentecostal, given that she is a chaplain.That would depend upon whether she ever claimed to be Pentecostal or Christian, and whether her baptism was contingent upon her claiming such.
I think it's fairly safe to assume she claimed to be Pentecostal, and by extension claimed Christianity, when she sought endorsement by the Pentecostals.
If she completed her duties as a Pentecostal preacher and did not try to convert anyone to Hinduism during that time, what's the problem?
Do you honestly believe that everyone that sits in the pew on Sunday believes in God? Do you believe everyone behind a pulpit believes what they are preaching?
Don't kid yourself.
This woman just came clean about what she believes, while others will lead a lifetime of deceit.
