I also began the survey and decided to stop. Simply put, the survey is going to be way too much data from way too many people. I began to ask, "Will my reply even be read - it is impossible." And if it is read alongside others, whose wins? Regardless of its final theological form (which I am sure will be faithful - like the current document), it is, in its very nature, biased toward a bigger explanation. Not all of us want that. In the survey, I felt like I was in the shoes of those who will eventually be the intended primary recipients of the text, "This isn't for me."
This is ironic and I hope we acknowledge the fact. If we are moving in this direction because “many changes in the understanding of morals, civil law and natural law in church and society” have come about, we also must acknowledge that we are impacted even more in our congregations by confirmation children who do not read. Visit any Goodwill, Half Price Books, or Salvation Army near a Lutheran church and you will probably find a Luther's Small Catechism with explanation. I am typing at my computer now with one of those "redeemed Catechisms" (from a former student of mine), by my desk and plan to mail it for the child's HS Graduation gift with a Gospel oriented pastoral card.
I want to know if it would it at all be possible to publish a version of the Small Catechism in hardcover apart from whatever explanation is finally decided upon. My background is Sec. Ed. and Manufacturing and I serve a rural parish that is becoming less rural each season. I am seeing a major, major shift in our young people where they are totally lost and swimming in (for them), the episodic experience of questions and proof texts. Because the explanation does not sequentially parallel the Biblical narrative they do not bond with either the Catechism or the Bible. I use the Bible in Confirmation and frame each article of the faith in a literacy model so that the articles of the faith are akin to vocab and the Biblical narrative is the Grammar. I am aided by the CPH paper copies of the Small Catechism (tract edition) but they wear out quickly as I instruct the kids to take them wherever they go. A small hardcover edition would be helpful.
I can see the current project already being very prone to scope creep and feel like the final form will not take into account the learners in our public schools today - who, btw, don't even learn how to write in cursive anymore and often submit assignments via computer starting in early grade school. The goal seems to be one of creating a textually exhaustive exposition, rather than a pastorally effective tool. That is fine, and it is necessary to have such a theological record for higher level discussions, but our pastors are already trained to address "many changes in the understanding of morals, civil law and natural law in church and society" using the Bible alone, aided by the Small Catechism in its original form. If we are struggling there, we might consider a renewal in using the Large Catechism.

In Christ and for the sake of the least among us...
