These matters concerning Luther’s understanding of the Biblical Second Commandment, needed some correction by Calvin and Calvinism. Correction is here needed also by Modern Evangelicalism, which at best is basically Sub-Lutheran rather than Truly-Calvinistic.
And here is the needed corrective! The 1647 Westminster Confession of Faith declares14 that “the acceptable way of worshipping the true God is instituted by Himself, and is so limited by His Own revealed will that He may not be worshipped according to the imaginations and devices of men or the suggestions of Satan under any visible representation or any other way not prescribed in the Holy Scripture. Deuteronomy 12:32; Matthew 15:9; Acts 17:25; Matthew 4:9f; Exodus 20:4-6; Colossians 2:23.”
