A girl (or woman) reading a passage from the bible as part of the service caused you to walk out?
Wow. You probably would have walked out of many an early New Testament church as well, since we know from scripture that prophesying and tongues speaking/interpretation of tongues are not gender specific gifts.
"As in all the churches of the saints, the women should keep silence in the churches. For they are not permitted to speak, but should be subordinate, as even the law says. If there is anything they desire to know, let them ask their husbands at home. For it is shameful for a woman to speak in church."
-1 Cor. 14: 33b-35
