As the "field-test" edition of the new version of the Explanation of the Small Catechism has been sent out to all Missouri Synod pastors and congregations, I expect (or at least hope) that pastors especially will take this opportunity seriously to look at the work of the committee.
Two specific things that I am doing as I review the new version, and I would recommend to others as well, are:
1. Read the coordinate section of the Large Catechism before and after each section.
2. Compare the proposed new version to the older versions. I would not only look at the most recent/current version, but also the 1943 and 1912 versions of the synodical explanation. The current version and 1943 versions are reasonably easy to get your hands on, but it is less likely for folks to have a physical copy of the 1912 version.
Fortunately, you can find the 1912 German-English edition online here.
