She is simply as God requires being honest, not bearing false witness. Coming out isn't about suddenly "becoming gay" -- it's about a change in others' awareness that you always have been gay. It doesn't change the fruits she has born and will continue to bear in ministry, which are gifts of the Spirit.
As a scholar of religion who is gay (and -- by the way -- currently celibate), I staunchly oppose this heretical Christian claim that the rare spiritual gift of and vocation to celibacy is automatically to be assigned to an entire group of people merely because of their affectional or sexual orientation.
Hell-busters exude the Spirit. They give off a Christ-like spirit. When you're in their presence, you can almost smell holiness. But the holiest of holy smoke has a tinge of the burnt smell with it. It's a smell that tells you it's been slightly singed near the fires of burning flesh and souls on fire.
