Marriage and the Book of Confessions

Would it be permissible for the PCUSA to interpret and/or amend the Book of Order section on marriage to reflect the reality of same-gender marriage, even though The Book of Confessions uses the language of “a man and a woman”?

Based on the way the Confessions have functioned in the church – especially since 1967, when a collection of documents was substituted for the Westminster Confession – yes. The Book of Confessions is not a compilation of proof-texts from which to glean answers to questions not contemplated by the authors, and contains numerous examples of assertions that are no longer appropriate or necessary expressions of our faith. General Assemblies have taken actions in the past that are directly contradictory to the letter of the Confessions.
