I agree that was their focus. Sometimes error is simply a matter of stretching one truth and ignoring others (to paraphrase Spurgeon).
As I have said, I held, preached, taught, and believed the Penal Substitution Theory of Atonement for decades. Throughout seminary this was my belief. As a preacher this influenced my sermons. As a teacher it influenced my teachings. Teaching theology, I presented the necessity of this view.
I have read the Puritians. I have read Calvin's Institutes, John Knox, John Owen (one of my favorites) and Jonathan Edwards (another favorite. especially The Freedon of the Will).
I understand your position. I get Penal Substitution Theory.
But it is not in the Bible. Not only is is not in Scripture, but it stands in opposition to Scripture more than any other major view of the Atonement. And it falsely colors so much of Scripture.
I was no less saved when I believed Penal Substitution Theory than I am now.
I can still "see" the Theory in Scripture, but only as an error I once carried there. The Penal Substitution Theory of Atonement cheapens grace and downgrades the character of God.
That said, since God moved me from that Theory towards a greater appreciation and understanding of Scripture I have a better grasp on the work of Christ as presented in the Bible which has encouraged spiritual growth that would have been impossible under the false teachings of Penal Substitution Theory.
I have not wrestled with the fact Penal Substitution Theorists are saved. I was once one. But I have wrestled with the fact many professing Christians cling to the Theory after being exposed to the truth of Scripture...after others pleading with them to shake off "worldly wisdom" and simply read God's Word.
Look at this thread. How many times has
@agedman and I been insulted or belittled for sticking to the text of Scripture and denying what others believe those text "teach"? It is not a big deal for me (
@agedman and I are not what is important here). What is important is what is (and is not) contained in God's Word.
