Cronos I think you are barking up the wrong tree here. PCA and OPC were formed as a reaction to the creeping (or in many cases not so creeping but speedy) advancement of heterodox modernism within the PCUSA. This is the true corruption that was besetting that church and led to such things as denial of the Virgin Birth, advocating for homosexual unions and abortion. The PCUSA as many other mainline Protestant denomination had seen the Zeitgeist and declared it good. Not only good but the new gospel.
That some members reflect very badly on these denominations should not be held against these bodies. We do not agree with their theology but they are truer in their faith statements and practice to historic Reformed teaching than the current leadership of PCUSA. That is the standard they should be judged upon.
For the writer of the article suggest they are corrupt because they allow the playing of musical instruments shows a degree of legalism that makes a mockery of Agape love. Indeed it raises my suspicions that there is more to the story. More as in “non flattering to the author”.
LC —> I just posted an article. this is the viewpoint of the author who has taken his anti-everything viewpoint from the PCA, OPC to it’s logical conclusion and is now anti-PCA.
