It’s inappropriate for you to imply that people prefer the recent official and universal Catechism of the Catholic Church because it somehow promotes changes to Church teaching or confusion and sin regarding Church teaching.
The Catechism was a project of St. Pope John Paul II, and Cardinal Ratzinger who later became Pope Benedict XVI was very much involved with it also. Are you saying those two Popes, one a Saint, promoted “evolved” teaching or unclear thought? Like I said, inappropriate, and also not credible.
I myself prefer it because it is what the Church says we are supposed to use as a catechism. When you go to RCIA, the catechists don’t take out a copy of the Catechism of the Council of Trent and teach people from it. I follow the Church authority in this matter.
