Individuals, or small groups of people, even several million people, who have read the Catechism is not a substantial number based on the total number of Catholics.
I credit you for your efforts but cannot accept that as proof that Catholics, as a general rule, read the Catechism.
Once again, I am sorry if I insulted you.
The "Renew" adult education courses that are being used in many Catholic parishes now are based on the Catechism. They lead the students through the basic outline of the Catechism, with guides for discussion and further reading.
The courses are very popular in our parish, they are usually full. According to Renew, 20 dioceses and 7 archdioceses are participating in this program. So you can do the math = a bunch of Catholics who are reading their Catechism in detail.
As for the kids, I know they learn the Catechism in Confirmation class because I sat through a good part of it, plus they had a Catechism review course for the parents of confirmands, and I attended that too.
My daughter is teaching a Renew course at her college in Charlotte NC, one of the participating dioceses. They're getting around!
Just a question of interest here.
You got off on a tangent about the Catechism of the Catholic Church.
Does your denomination or sect have such a listing of beliefs as contained in the CCC?
