This is why I do not like loose subscription. If something in the WCF is no longer considered essential for church officers to hold to, then the denomination should revise it. Otherwise strict subscription should be enforced.
If you're actually implying or stating that the PCA is a "loose" subscription denomination, then, according to the WLC, you are violating the 9th commandment.
Loose subscription would have accurately described the old Southern Presbyterian Church, where even among conservatives you had Arminians, charismatics, and dispensationalists.
The PCA achieved something astounding --to take the very diverse evangelicals in the Southern church, and meld them into a denomination that actually took the Confession seriously, particularly on matters of soteriology.
Thus, you will not find ARminians or dispensationalists in PCA pulpits today, some scant 35 years later.
The PCA is a subscriptionist denomination --every bit as subscriptionist as the OPC. But, it does allow men to hold differences with the WCF, as Professor Murray did.
LEt me ask a question: Do you believe the covenant of grace is made with believers (affirming a separate pactum salutis), or with Christ (seeing the pactum salutis as unnecessary)? To which of those positions do you subscribe? The confession says both. Which is the subscriptionist position?
