When the English-translation of  CCC first came out 1n 1994, a number of good Catholics bought copies from a local parish.  A number of people spoke to me about 3 weeks later stating that they struggled getting through the first section of part 1 "The Profession of Faith I believe" "We believe".  And they told me that they found the CCC as dry as sand.  Most of them never got beyond where they stopped.

Most parents of growing children have never consulted the CCC for advice.  Why should they?  The people who wrote the CCC have no practical experience raising children, themselves.  There are many other good Catholic sources in helping parents to understand how to impart the faith to their children.  And these are written by actual parents of children.

For ordinary Catholics, the CCC is obtuse and obscure.  It wasn't written for ordinary people to begin with---but for teachers [bishops and those educated in Religious formation].
