Clearly you didn’t read the Fourth Baltimore Catechism. There are four, and the larger the number the more in-depth of an answer it provides to the questions. If you read number one, then yes the above would apply. Number four however, gives way more in-depth answers, so if you haven’t read that one, you haven’t gotten the whole thing.
The Baltimore Catechism was / is aimed at the laity … lay people of all ages, all educational levels, and of all “school years”. The first volumes are aimed at elementary school. It was prepared in response to what was correctly perceived as a gap in knowledge by the laity.
The CCC is written extensively and is more suitable for clergy and diocesan staff to prepare local papers and discussion pieces … as well as for serious students who have the time and education to go over the discussions contained therein seriously.
Most people with jobs, kids, family, bill juggling, and all the rest arguably don’t have the time or energy to refer to the CCC on a regular basis.
The Baltimore Catechism is designed for kids and people with kids, etc. … although the Baltimore Catechism may or may not need some updating to bring it into conformance with the seemingly never-ending changes to daily practices … e.g., fast & abstinence, holy days of obligation, etc, etc.
The Baltimore Catechism explains the core nuts and bolts … Transubstantiation … sainthood … sacraments versus sacramentals … the parts of the Mass. It explains things in language that people can easily remember for decades and understand clearly … and repeat back decades later. The Baltimore Catechism is a workable and usable document for the working person.
The Baltimore Catechism may not be perfect, but it provides some sustenance and some substance for people who have lives with many parts and with the push-pull demands that pure scholars don’t have to worry about.
The Baltimore Catechism is better than the nothing that we have had to live with for the past two generations of Catholics.
CERTAINLY, the Baltimore Catechism is better than coloring pages with crayons and making banners.
