If we were talking the substance everyone here would be in agreement in condemning it. Fred's point w.r.t. American cousin denominations is not without merit, but my point stands I think. The Westminster Standards are the historical documents of Presbyterianism, like the constitution and declaration are to the USA. The PCUSA derived sister denominations have till something changes a shared text and history w.r.t the PCUSA revisions. And if the point raised just now, that this is going to mean a drive to adopted this in the PCA, it is nothing short of creating a scandal. I would not seek to leave a denomination that forced this, but I sure would not look to join one if I were looking for a move.Why not just learn Greek and Hebrew and read the scriptures in the original language instead of producing (fallible) translations of them in modern vernacular language? (Obviously I do not actually advocate this).
To be quite blunt, I do not see updating the language of the WCF as anything even remotely close to updating the substance of the WCF.
If the new thing the OPC makes contains the same ideas as the original WCF as writ, then it's the WCF.
