Are you trying to ask about the general principles the PCUSA (and yes, you should
edit your question to define that acronym, as @robertbristow-johnson says) uses to interpret scripture? Are you asking what the PCUSA believe about homosexuality, and how they support that belief with scripture? Are you asking about how the Bible
should be interpreted (on either or both of the above points)? Or are you asking all of these things at once? Basically, I think your question is unclear, and hence not useful. —
