I enjoyed reading this and agreed with the majority of it (though the parts I disagreed with, I really disagreed with). I've only ever read Luther's Small & Large Catechisms before, so it's good to get an alternate perspective. I would have liked to see more on law vs. gospel and the Word & Sacraments, but those are specifically Lutheran emphases so I'm not surprised I didn't.

A worthwhile and quick read. The first question/answer is worth memorizing.
