Hello, sorry you haven't had many replies, but the site goes through periods of inactivity. I'm no scripture scholar, but I'd say good examples of *possible* same-sex romances would be the Roman centurion and his slave, and Jonathan and David, who seem to have a deeper-than-most-dudes-are-comfortable-with kind of 'friendship.' Some scholars claim these were undoubtedly gay relationships. (I would caution that in a manuscript so old, so often re-translated, and interpreted in so many ways, nothing is "undoubted.")
I'd also point out to the people in that congregation you mention that scripture often appears to support slavery and the lesser status of women. Yet, surely no one there would argue against abolition, the civil rights movement, or women pastors, would they? Or for that matter, divorced and remarried pastors?
Besides, that, there are oodles and gobs of passages about not judging and loving your neighbor. ELCA Lutherans and Methodists believe we are saved by faith alone through grace alone. If two women in a romantic relationship have faith in Christ, who is to judge that faith? Is that faith any less salvific because they are gay? If one of them feels called to ministry, and is following Christ as best she knows how, why can she not be ordained? Why are gluttons, the greedy, the heterosexually lustful, and the arrogant ordained?
Sorry, I have no idea where to find the documents you seek, and I'm not even a churchgoer, but thought I'd take a stab at helping you.
