It's quite possible that you're right. Research would have to be done on it to test it. On the other hand, it still does not seem to me that Kline's formulations contradict the confession on this point. It may or may not be speculative. But that's what a discussion should find out. Who knows but what there might be biblical evidence to support Kline's ideas. Kline, after all, was an expert on the Holy Spirit, having written a book on Him that greatly expanded my conceptions of the Holy Spirit.
