For starters, I would say true Presbyterians affirm the infallibility of the Bible in the original autographs. I would also say they would affirm the Westminster Confession of Faith.
By supporting the ordination of women, abortions and homosexuality, I would say that “Presbyterians” who do so are being inconsistent with both Scripture and the Westminster Confession.
I'm not sure which of the Presbyterians have the "original autographs" to affirm, but I'm sure all Presbyterian denominations hold to the inerrancy of Scripture. It's just the variance in interpretation of those Scriptures that are at odds.
I would also say they would affirm the Westminster Confession of Faith.
Even the Presbyterian Church USA affirms the Westminster Confession of Fairth.
