I think it goes deeper than just “unlawful,” because contraception says that God made human beings wrong ... that when He looked at His completed creation, crowned by man and woman made in His image, and “behold, it was very good,” He was incorrect.
This is not just a technicality, “You say tomayto, I say tomahto,” but an issue that profoundly affects and reflects our understanding of God and His heart towards us.
Oh, now it's contraception that caused the Hahns to convert? How often do they change their story?
As for Kimberly, "At this point [more than halfway through seminary] I was not steeped in Reformation theology, so the change in how I viewed justification did not seem momentous". Please consider the import of that statement. Here are two graduates of a Presbyterian College, two students nearing completion of their studies at reputedly one of the best evangelical Protestant seminaries in the country, two professing Christians and the meaning of justification is not all that important to them. As we shall soon see, despite or rather because of their education, the Hahns especially Scott could not defend the Reformation principles of the Bible alone, faith alone, and Christ alone.
