Since the Westminster Standards include the most accurate statement of the Gospel yet put into confessional form, the bulletin writer implies that one can believe the Gospel and be a fake.
Any ridiculing of the Westminster Standards as being a Greek and Hellenistic, and therefore inadequate, interpretation of the Bible is ridiculing of Biblical Christianity in it purest human expression.
Vatican II, On Divine Revelation, Section 9: Therefore both sacred tradition and Sacred Scripture are to be accepted and venerated with the same sense of loyalty and reverence.
It appears to me as though the circle has closed. Those who view themselves as the strongest advocates of the Reformation have circled back around and turned sola scriptura on its head.
